Question

Accepted Answer

Java is a popular programming language known for its platform independence and object-oriented approach.

Java is platform independent because it uses the concept of bytecode and virtual machine (JVM).
Bytecode is a platform-neutral code that can be executed on any operating system or architecture.
JVM interprets the bytecode and translates it into machine-specific instructions.
Java is not a pure object-oriented language because it supports primitive data types like int, float, etc.
However, everything in Java is an object, including classes, interfaces, and arrays.
Java provides features like inheritance, polymorphism, and encapsulation to support object-oriented programming.
Java's syntax and libraries are different from C++, making it easier to write and maintain code.
Java has automatic memory management through garbage collection, unlike C++ where memory management is manual.
Java has built-in support for multithreading, exception handling, and networking.
Example: In Java, you can create a class called 'Car' with properties and methods to represent a car object.

Accepted Answer

Java is a compiled as well as interpreted language, it is true object oriented programming language.

Java is plateform independent because in java after compilation source code is firstly converted into the byte-code and this byte-code is platform independent, with the help of this byte-code we can run our program on any platform.

Java is not pure object oriented because is support primitive data types.

Java is different from c++ because in "main" is present inside the class , but in c++ main is present out side the class.
