C++ AND JAVA

C++ supports OOP, while Java is OOP out of the box.

C++ supports multiple class inheritance, while Java only gives you a single class inheritance, but solves the multiplicity via interfaces.

C++ has got a pointers, and can directly manipulate/violate the memory addresses.

Java is a type-safe language, and you have no availability of pointers in Java. They're present in the background, but not on the scene.

Generics in Java, and templates in C++

Java does not include structures or unions.

Java does not support destructors but adds a finalize() method.

All the code in Java program is encapsulated within classes therefore Java does not have global variables or functions.

C++ requires explicit memory management, while Java includes automatic garbage collection.
