What are the different features of Java?
We tried to understand What is Java? We have touched upon Java features. Let’s try to understand what they really mean
- Object Oriented – Java as a programming language, follows Object Oriented programming paradigm. Everything in Java is an object, except the primitive types. We will discuss more on this.
- Platform Independent / Portable / Architecture Neutral – Although these are considered 3 different features, but I have found they refer to the same thing. bytecode and JVM are 2 critical terms related to Java. We will discuss more on them but needs a little bit of introduction when we are discussing these Java features
- JVM is a platform-specific Virtual Machine capable of interpreting bytecode to machine code. Platform-specific means, we have different JVMs for different systems depending on the underlying architecture, operating system, etc
- Unlike C and C++, irrespective of platform-specific machine code, Java generates platform-independent bytecode after compilation. This bytecode can be interpreted by any JVM in any system to fulfill Write once, run anywhere (WORA) slogan
- With the help of bytecode and JVM, Java becomes platform-independent, portable, Architecture Neutral whatever you say
- Secure – With the help of JVM and some other technologies, Java provides a closed environment inaccessible from outside, making code execution more secure than ever before.
- Robust – Java code is compiled to bytecode, then bytecode is interpreted to machine code by JVM during code execution. Java provides an exhaustive error-handling mechanism during compile time as well as runtime in the form of Exception-handling
