java is pure object oriented language whereas c++ not. java is not invented to replace c++ it's invented to solve other kind of problems related to network there r lot of difference in both, consider through any book.

Through Java we can develop distributed / Internet based applications, whereas it is not possible with C++. 
In Java main() method will be inside the class whereas in C++ it is outside the class.

hi

the main difference between c++,java is c++ is a semi object oriented programing language where as the java is fully object oriented language,java is platform independent also,then java memory allocatin and deallocation is easy,garbage collection is one of the features,a rich set of collection api

C++ has templates but Java doesn't;C++ can pass by value(default) or by reference whereas Java can only pass by reference (well, except primitives);C++ supports multiple inheritance but Java doesn't (although multiple interfaces);C++ requires memory management and Java provides garbage collection;C++ has pointers and Java doesn't;C++ is system dependent and Java is system independent

How you say java is more secure without pointers? Without pointers,java is not difficult to learn.I jst need how it is secure?

Java interprets codes, codes written in Java are portable between platforms, but C++ compiles codes, codes written in C++ are MUCH faster.

Hey java uses pointers but don't gives authority to create and change any pointer within java.java uses implicit pionter.All the objects in java have pointer as a reference internally.

c++ supports structures,union and enum concept whereas java doesn't.
c++ uses compiler, java uses interpreter.
C++ is plateform dependent, java is plateform independent.
c++ uses preprocessor directive. java do not use preprocessor hence no need to  include header files and no concept of macros.

1 - Java does not support operator overloading
2 - Java does not take template
3 -
It does not support multiple inheritance, however in internet it users multiple inheritance
4 -
Java does not support global variable
5 - Destructor are not used in Java

Where all these 5 statement are possible in C++

Since Java does not have a preprocessor there is no concept of #define macros or manifest constants. However, the declaration of named constants is supported in Java through use of the final keyword

Even though both C++ and Java are object oriented programming language, C++
is not platform independent, whereas Java is platform independent. C++ will not
support string data type directly (we have to give array of characters) , but in
Java there is one class called String. It will support data type. C++ will
support multiple inheritance, but in Java multiple inheritance cannot be
supported in order to avoid duplication

1. Multiple Inheritance is also possible in Java through Interface.
2. The first argument in C++ command line argument is the name of the file while in Java its any type OS input
