The latest version of Java Standard Edition is Java SE 8. With widespread popularity, Java is configured and integrated into various platforms. For example, J2EE for enterprise applications, J2ME for mobile applications.
The newer J2 versions have been renamed to Java SE, Java EE, and Java ME. A characteristic of Java is write once, run anywhere. A basic guide to the Java language will help you understand its history and application capabilities.

Features of Java include:
- Object-Oriented Programming: In Java, everything is an object. Java can be easily extended as it is based on the object model.
- Platform Independence: Unlike other programming languages like C, C++, when Java is compiled, it is not compiled into a specific computer platform, but into an independent bytecode platform. This bytecode is distributed over the web and interpreted by the Java Virtual Machine (JVM) on the platforms it's running on.
- Simplicity: Java is designed as an easy-to-learn, easy-to-understand programming language. Once you grasp the basic OOP concepts of Java, you can easily master it.
- Security: Java's security features allow for the development of virus-free systems as well as freely available counterfeit-proof systems. Authentication techniques rely on public-key encryption.
- Architecture Neutral: The Java compiler creates an architecture-neutral object file format, allowing compiled code to be executed on various processors with the presence of the Java operating system.
- Portable: Being architecture-neutral and having no platform-specific aspects makes Java a portable programming language. The Java compiler is written in ANSI C with mobility capabilities.
- Powerful Programming Language: Java strives to eliminate error-prone cases by performing compile-time error checking and runtime verification.
- Multithreading: With Java's multithreading feature, you can write programs that perform multiple tasks simultaneously. This feature is designed to allow developers to build interactive applications that run smoother.
- Compilation: Java bytecode is compiled directly to machine code and not stored in any location. This speeds up development and analysis processes.
- High Performance: By using the Just-In-Time compiler, Java provides higher performance.
- Distribution: Java is designed for Internet distribution environments.
- Dynamic: Java is considered more flexible than C and C++ because it is designed to adapt to the evolving environment. Java programs can carry a large amount of runtime information, which can be used to verify and resolve accesses to objects at runtime. Through the article differences between Java and C# you will see that Java has many differences from other languages.
History of Java Development
Java's creator is James Gosling, one of the first people to participate in the Java language development project in June 1991. Initially, this programming language was called 'Oak', a common tree in countries like the United States, ... and was developed as part of the Green project. It was later renamed Java.
Java was first released by Sun in 1995 (Java version 1.0). Java's feature is write once, run anywhere, providing faster runtime on popular platforms.
On November 13, 2006, Sun released Java as free software and open-source under the terms of the GNU General Public License.
On May 8, 2007, Sun completed the process, creating a free and open-source Java codebase, except for a small portion of code that Sun did not own the copyright to.
The tools you need
To develop GNU, network, and web applications using Java, you need:
- Pentium 200 MHz computer, minimum 64 MB RAM (recommended to use 128 MB RAM).
This basic guide to the Java language will provide the necessary skills to create GUIs, networks, and web applications using Java.
Additionally, you will need software:
- Operating system Linux 7.1 or Windows XP/7/8.
- Java JDK 8.
- Microsoft Notepad or other text editors.
