As a popular programming language, Java is used in a wide range of development projects. Here are key things to know about Java development:

  • The Java platform is versatile and can be used for developing a variety of applications, from simple desktop programs to complex web-based applications.
  • Java development tools make it easy to write, debug and deploy Java code. Popular Java development tools include the Eclipse IDE and the NetBeans IDE.
  • To run a Java program, you need a Java runtime environment (JRE). A JRE includes a virtual machine that enables Java code to run on your computer.
  • The most recent version of Java is Java 8, which was released in March 2014.
  • Oracle is the primary provider of Java development tools and resources. However, there are a number of other companies that offer Java-related products and services, including IBM, Red Hat, and JetBrains.
  • If you’re new to Java development, it’s important to get started with the right tutorial or resource. The official Oracle documentation is a good place to start, but there are also many excellent third-party resources available online. 
  • When working on a Java development project, it’s important to be aware of the various licensing options available for using Java. For example, Oracle provides two different types of licenses for using Java: the Oracle Binary Code License (BCL) and the Oracle Technology Network License (OTN).
  • There are a number of different Java development frameworks to choose from, including the Spring framework, the Google Web Toolkit (GWT), and the Apache Struts framework.
  • In addition to IDEs and frameworks, there are a number of other tools that can be helpful when working on Java development projects, such as build tools (such as Ant and Maven) and debugging tools (such as the Eclipse Debugger).
  • When working with Java code, it’s important to adhere to best practices in order to avoid common mistakes. Some of the most important Java development best practices include using coding conventions, writing comprehensive unit tests, and following design patterns. 

What Are the Main Basics of Java?

Java is a powerful and versatile programming language that allows developers to create robust, high-performance applications. The Java platform is designed to provide a complete development environment for creating, testing, and deploying Java applications. In addition to the Java virtual machine (JVM), which enables Java code to run on any compatible system, the Java platform includes an extensive set of libraries and tools that help developers write, debug, optimize, and deploy their applications.

The main basics of Java include

  • Object-oriented programming: 

Java is an object-oriented language, which means that it uses objects and classes to represent data and functionality. This allows for more modular and flexible code development, as well as better code reuse.

  • Platform independence: 

Java code can run on any system that has a compatible JVM. This makes Java applications much more portable than those written in other languages.

  • Memory management: 

Java automatically manages memory, which helps avoid common programming errors and can lead to more efficient code.

  • Security: 

The Java platform includes a number of features that help ensure the safety of applications, including security sandboxing and bytecode verification.

  • Robustness: 

Java’s exception handling and type-checking mechanism help prevent many common programming errors.

  • Multithreading: 

Java’s support for multithreading allows developers to write programs that can take advantage of multiple processors and perform multiple tasks simultaneously.

The Java platform also provides a wide variety of libraries and tools for developers to use. The Java Development Kit (JDK) includes everything necessary to write, compile, debug, and deploy Java applications. The Eclipse IDE is a popular tool used by many Java developers. And the Apache Maven build system can be used to manage dependencies and automate builds.

These are just some of the basics of Java. If you’re interested in learning more about this versatile programming language, check out our Introduction to Java Programming course. It covers all the essential topics you need to know to get started programming in Java.

What Are the Main Features of Java?

The Java platform provides a comprehensive set of libraries and tools that enable developers to write efficient code, while its runtime environment helps ensure that applications are safe and secure. In addition, the Java platform provides a rich set of features that makes it an ideal choice for developing enterprise applications.

Some of the main features of Java include:

  • Object-oriented: 

Java is an object-oriented programming language, which means that code is organized around objects rather than actions. This makes it easier to develop large, complex applications.

  • Platform-independent: 

Java code can run on any platform that supports the Java Runtime Environment (JRE). This makes Java applications portable, meaning they can be run on any operating system.

  • Security: 

The Java platform provides a number of features that help ensure that applications are safe and secure. For example, the Java Virtual Machine (JVM) uses a security manager to help protect against malicious code.

  • Multi-threaded: 

Java supports multiple threads of execution, which means that hiring dedicated developers can write programs that can perform several tasks simultaneously. This makes Java ideal for developing concurrent applications.

  • High performance: 

The Java platform is designed to provide high performance. The Just-In-Time (JIT) compiler helps improve the performance of Java applications by compiling code into native machine code at runtime. In addition, the garbage collector helps reduce memory overhead by reclaiming memory from unused objects.

  • Extensibility: 

The Java platform is designed to be extensible, which means that developers can write their own libraries and tools that extend the functionality of the platform. For example, the Java Database Connectivity (JDBC) API allows developers to access databases from within Java applications.

  • Rich set of libraries: 

The Java platform provides a rich set of standard libraries that cover a wide range of functionality, including input/output, networking, security, and more. This makes it easy to hire app developers to find the library they need for any given task.

  • Interoperability: 

Java applications can interoperate with applications written in other programming languages. For example, the Remote Method Invocation (RMI) API allows Java applications to call methods on objects located in other JVMs.

  • Portability: 

As mentioned earlier, the Java platform is designed to be platform-independent. This means that applications written for the Java platform can run on any system that supports the JRE. In addition, the Java platform is designed to be architecture-neutral, meaning that applications can be deployed across different types of hardware.

To sum up, the main features of Java include being object-oriented, platform-independent, secure, and high-performance. These features make Java an ideal choice for developing a wide range of applications.


As we have seen, Java development is a complex process that requires a lot of knowledge and experience. This article has looked at some of the key things you need to know about Java development. Hire java developers for your project requirement to reduce your time and cost. We hope that this article has been helpful and that you now have a better understanding of the process.
