  • JAVA is used to create windows apps, utility programs, networking essentials and many more.

Features of JAVA:
  • Simple
  • Object-Oriented
  • Robust
  • Secure
  • Platform independent
  • Portable
  • Multi Threading

Simple: Java is more simple than C++. Syntax are easy to understand. There are no more complex concept like Operator overloading and Pointers in Java.

Object-Oriented: Java follows the concept of object-oriented where each object has some properties and behavior.Object-Oriented concept has some features like class, object, Data encapsulation, Inheritance, Polymorphism etc.

Robust: Robust property helps to eliminate errors using check errors at compile time as well as run time and Exception Handling.

Secure: Secure feature let java be virus free and temper free. As there is no concept of pointer in java so security feature is enabled.

Platform Independent: Platform Independent means that once we compiled java program, it generates bytecode of it. We can run this bytecode in any system of any operating system without installing JVM.

Multi Threading: In java one program can do many works simultaneously. Multi Threading property helps to use more resources in less time.
