Java Programming Software

Java is developed using the Oracle Java Development Kit (JDK). The most popular version of the JDK which is typically used for application development and in coursework is Java Standard Edition (SE) version 8. To get started developing Java using the JDK, download JDK 8 here , selecting the version corresponding to your operating system.

After downloading the Java Development Kit (JDK), an integrated development environment (IDE) is used to write code in the Java programming language. There are a number of popular tools which are commonly used for Java software development.

Popular Java IDEs:

  • Eclipse:
  • NetBeans:
  • IntelliJ IDEA:
  • BlueJ:
  • DrJava:
  • JCreator:
  • jGRASP:

Among the options for development environments, Eclipse is the program of choice which is most commonly used for Java program development. Eclipse is an open-source IDE which supports the creation of Java workspaces for more complex Java development projects, and it supports the development and use of plug-ins which extend the core functionality of the program. Download Eclipse now to begin writing programs in Java.

Java source code is organized in classes, in which each class either contains code which can be executed, or contains the definition of a class, which can be referenced and instantiated by another class in the program. Within a program, these classes belong to packages where each package is a grouping of classes that contain a common set of roles, functions, and objectives. Part of becoming a great software developer involves thinking about how best to organize your code. Plan a program out in advance using pseudocode or a skeleton of the overall project. This will help you identify what packages and classes will be needed in the overall program, as well as guiding you to consider how the different parts of the program will depend on and affect each other.

Now that you have the Java Development Kit, the Eclipse integrated development environment, and a program in mind, you have all the tools needed to dive into Java programming. Whether your program is an introductory level Java assignment or a more complicated graduate-level algorithms project, our Java online tutors are ready to assist with your Java programming assignment to help you design and create great software.

About Java Programming

The Java programming language was developed by Sun Microsystems and first released in the year 1995. It is a powerful, high-level, general-purpose programming language. Java is based on the principle of write once, run anywhere and hence is a platform-independent, architecture-neutral, portable, and robust programming language.

It is the second most popular language among developers with over 12 million developers running Java. It runs on more than 3 billion devices worldwide including the Android operating system. It has grown from humble origins to power a significant portion of today's digital world by offering a secure platform on which many software applications are built. Java is still used in new, innovative goods and digital services that are being developed for the future. Many apps, including some websites, will not work unless you have Java installed.

Importance of Java

Java is a general-purpose programming language. It is used on mobile phones, desktop computers, and large-scale industry servers and applications because of its stability and scalability. It has recently gained popularity in the Internet of Things (IoT) and cloud development fields. There are around 10 million Java developers worldwide, and this number is growing on a daily basis. Java, like other open source technologies, promotes the idea of giving back to the community.

Java is more common than you might assume in your daily lives. Google, YouTube, LinkedIn, Amazon, and eBay are just a few examples of popular websites that employ it. It also has a solid development path, with security and performance improvements being made on a regular basis.

Why is java so Popular ?

Platform independence is one of the main reasons for Java's popularity. Java programmes can operate on a variety of computers as long as they have the Java Runtime Environment (JRE) installed. Another reason for java’s popularity can be that the code you wrote 15 years ago will execute on the most recent JVMs, benefiting from the latest profiling, native code translation, and memory management. In addition, Java is an object-oriented programming language Object-oriented programming is at the core of Java. Because Java objects don't refer to data outside of themselves, the code is extremely robust. Lastly, even though the language is considered basic, it comes with a library of classes that provide often used utility functions that most java projects require.

Is Java Worth Learning ?

Java is still a useful programming language that shows no signs of fading in popularity, making it worthwhile to learn. As it is very simple to learn, most developers use it as their first programming language. Java has an English-like grammar with few special characters, therefore, it can be learnt quickly and utilised to create useful applications. Because Java is part of a family of languages that are significantly impacted by C++ (as well as C#), knowing Java can help you learn these other two languages more quickly. Some examples of areas where java is used are Android applications, web applications, software tools, and scientific applications.

According to Indeed , an Entry-Level Java Developer can start with an annual salary of around $66,000 per year in the US.

Which Java Concepts are Most Difficult?

The following are some subtopics with which students usually face problems, and our Java programming professionals can help you with them:

  • Object-Oriented Programming (OOP): Imagine Java as a language that revolves around creating and manipulating objects. These objects are like building blocks that interact with each other. Understanding how to design and work with these objects, inheritance (where one class can inherit attributes and methods from another), polymorphism (the ability to use different objects interchangeably), and encapsulation (keeping the inner workings of an object hidden) can be a bit like learning a new way of thinking.
  • Generics : Think of generics as a way to create flexible and reusable code. However, they can be a bit like solving a puzzle. You need to figure out how to write code that can work with different types without knowing the exact type beforehand. This involves understanding concepts like wildcard types, type bounds, and type erasure.
  • Concurrency and Multithreading: Picture a scenario where you have multiple tasks running simultaneously, like a juggler juggling multiple balls at once. Java provides tools for managing these simultaneous tasks, but it can be challenging to ensure they don't collide and cause issues. This involves concepts like synchronization and making sure your code is thread-safe.
  • Exception Handling: Imagine you're programming and something unexpected goes wrong, like your program trying to divide by zero. Exception handling is like setting up a safety net to catch these unexpected errors and deal with them gracefully. It involves handling different types of errors and deciding what to do when they occur.
  • Lambdas and Functional Programming: Java introduced a more modern way of programming called functional programming. It's a bit like learning a new style of writing. Lambdas allow you to write code more concisely and in a functional style, which can be different from the traditional procedural style of programming.
  • Classpath and Package Management: Think of Java code as a library with many books (classes and packages). You need to organize these books in the right order and make sure you can find them when you need them. This can involve configuring the classpath and understanding how packages and modules work.
  • Garbage Collection: Java helps you manage memory automatically, a bit like a magic cleanup crew. However, understanding how it works under the hood and optimizing it for performance can be challenging.
  • Design Patterns: Think of design patterns as proven blueprints for solving common problems. Learning them is like understanding architectural plans for building different types of houses. These patterns help you write maintainable and scalable code but can take time to grasp fully.
  • I/O Operations: Working with input and output in Java is like connecting pipes to move data around. You need to know how to read and write data from files, streams, and other sources efficiently.
  • Java Virtual Machine (JVM): The JVM is like the engine that runs your Java code. Understanding how it manages memory, executes bytecode, and optimizing its performance is a bit like learning about the inner workings of a car engine.

Frequently asked questions

Java, as a programming language, has  a number of inherent features  that make it secure. The platform itself includes security measures such as strong data typing, automatic memory management, bytecode verification, and secure class loading. These inherent platform features make Java relatively secure by default.

In addition, developers can opt to add additional controls like cryptography, authentication, authorization, Public Key Infrastructure (PKI), secure communication, and XML signatures. While all of these security controls are readily available to add to your Java program, you must know to include them in the first place; they are not automatically enabled.

While Java’s built-in security measures are robust, it still has gaps that must be addressed by your teams. For instance, using a framework to build your Java application introduces the possibility of  new vulnerabilities .  Dependencies within your application also open up your software to possible risks. Because of this, your team needs to be aware of  which dependencies  your software includes, and whether or not they are secure. A tool like  Snyk Open Source  can uncover which dependencies are interconnected with your application, enabling your team to remediate or replace insecure components.

Java programs should be written to be clean and straightforward. Clean, quality code means that:

The order of execution, from beginning to end, makes sense logically and structurally

It’s easy to understand how the different parts of code interact and work together

Each class, function, method, and variable has a clear role. They are all clearly named.

Classes and methods only fulfill one task and work as expected

When your code is built cleanly from the start, it’s easier to read, less prone to errors, and, by default, more secure. A few other ways to build high-quality Java code include avoiding hardcoding, maintaining thorough logs, turning repetitive code into a separate class or method, and only using a few parameters for each method.

The key to good quality Java code: Write it so that when someone else opens your project, they can see the documentation, and as a result, understand how it all works.

Creating high-quality, secure code is easier said than done. Using an automated code checker is the best way to improve code quality and security practices.

A code checker analyzes your code, checking its syntax, style, and documentation completeness. A  security-focused code checker  will also check system configuration, data flow, semantics, and structure for possible security issues. Because of this, many organizations use code checkers to perform  static application security testing (SAST) .

A Java code checker should be able to do the following:

Integrate into your developers’ existing processes

Seldom return false positives or negatives

Flag the issues by specific line

Scan source code at every stage of development (a DevSecOps approach )

Combine with other code quality tools, such as linters

Reference a comprehensive database of vulnerabilities

Go beyond flagging quality or security flaws by also giving actionable suggestions on

 how to fix them

Secure development requires a security-from-the-start mindset. Security measures need to be added into the very beginning stages of your development lifecycle, all the way up until production. Waiting until the end of the cycle to remediate security issues will cause your developers to backtrack and examine code that was written weeks, or even months ago to identify and fix what went wrong. It will end up costing far more than remediating these issues earlier in the process.

Instead, a Java code checker enables developers to create a  secure software development lifecycle (SDLC)  by giving them the ability to automatically scan code in small batches, just minutes after it’s written. Code checkers integrate well into other automated processes, such as  CI/CD pipelines , and help teams to ensure that their code is clean, easily readable, and free of bugs and security errors.

A syntax error occurs when a Java parser cannot comprehend the command you are trying to execute because your code does not adhere to the programming language’s rules. Because Java is a compiled programming language, this error prevents the code from being compiled and therefore, keeps it from running. Often, this is caused by a misspelling, a missing punctuation mark, or an undefined variable.

Common Java syntax and logical errors

There are a few common syntax and logic errors that your Java code checker will find. Regardless of how experienced your developers are, they still might fall into some of these common syntax issues, simply because they’re human and these mistakes are easy to make. Here are a few common errors:

Using a variable, but failing to define it or misspelling it

Missing a symbol such as a semicolon, quotation mark, or parentheses

Attempting to assign values to incompatible variables (i.e. assigning a decimal value when the variable can only process integers)

Trying to use a type that does not exist, is misspelled, or cannot be easily located by the program.

An AI-powered Java code checker catches errors and vulnerabilities more quickly and accurately than manual checks such as peer code reviews or pair programming. To facilitate artificial intelligence, the code checker is trained by hundreds of thousands of open source projects. In other words, an AI-powered code checker can comprehend what’s “normal” for Java programming and use this knowledge to find quality and security errors, then provide intelligent suggestions for remediation. As a result, developers can find and remediate code errors, intelligently and automatically. Snyk code is one of the fastest solutions for checking your code, and enables fast feedback cycles and iterations for continuous improvement. It can also help your developers learn more about security as they code, with fix suggestions and explainers.

Check your Java code, right within your existing workflows.

Secure your Java code as you develop.  Snyk’s free IDE plugins ,  including Intellij ,  scan your Java code for risk and quality errors, then provide actionable insights to help you fix them.

Secure your Java code as it’s written

with static application security testing built by, and for, developers.

In the future more will be added but there is no specific plan since I am developing them in my spare time.

Please note the following:

  • Each solver is provided to you for free but they are unsupported .
  • Each solver has not been extensively tested. It should generate correct results for simple examples but may have errors in complex situations.
  • If you have found a bug, use the contact form to send it to me. If I have spare time I will look into it.
  • Most solutions are based on examples provided by tutors at University Of Athens (UoA) or at Athens University of Business and Economics (AUEB). If you are studying in a different University the expected methodologies by your tutors may not be entirely the same.
