The Java programming language has the following features:
- Simple: Java is a simple language to learn. Because Java's syntax is based on C++, it is easier to write programs in it.
- Object-Oriented: Java adheres to an object-oriented paradigm, which allows code to be maintained as a collection of objects of various types that contain data and behavior.
- Portability: Java supports a read-everywhere, write-once approach. Java programs can run on each machine. Java programs
(.java)are converted to bytecode(.class)so that they can be executed on any machine. - Platform independent: Java is a programming language that is platform independent. It differs from other programming languages that require platform execution, such as C and C++. Java includes a platform for running its code. Java does not require an operating system to run.
- Security: Java is secure because it does not employ explicit pointers. To improve security, Java includes the concepts of byte code and exception handling.
- Robust: Java is a powerful programming language due to its strong memory management. It is made more robust by concepts such as automatic garbage collection, exception handling, and so on.
- Architecture Neutral: Java is architecture neutral because it does not depend on the architecture. In C, the size of data types can vary depending on the architecture (32-bit or 64-bit) that does not exist in Java.
- Interpretation: Java uses a just-in-time (JIT) interpreter and compiler to execute programs.
- High performance: Java is faster than other traditional interpreted programming languages because Java bytecode is "closer" to native code. It's still a bit slower than compiled languages such as C++.
- Multithreading: Java programs that process multiple tasks at once can be written by defining multiple threads. The main advantage of multithreading is that it doesn't take up memory for each thread. It shares a common memory area. Threads are important for multimedia, web applications, etc.
- Distributed: Java is distributed because it facilitates users to create distributed applications in Java. RMI and EJB are used to create distributed applications. This feature of Java allows us to access files by calling methods from any machine on the Internet.
- Dynamic: Java is a dynamic language. It supports dynamic loading of classes. This means that classes are loaded on demand. It also supports functions from its native languages, namely C and C++.
