java is automatic garbage collector where in c++ we have to use destructor to deallocate the memory.

any automatic memory deallocation. where as java have
automatic deallocation of memory

Answer / ashish saran
There are many differences between C++ and Java, but they are all having some kind of substitute for that in one another. for eg, Java is missing pointers but there are collections framework in Java for implementing data structures.Java is missing multiple inheritance but has interfaces for that.
The architecture of both languages differ. In C++ header files are used, while the whole architecture of Java depends on Classes(there are also advantages to that).
However the main differences are of Multi-Threading and Platform Independence which are only in Java. Also it is more Programmer friendly.

Answer / sandeep kumar
C++ is partial object oriented programming language because
without using a class we can write a program.
java is a complete object oriented programming language
because we cannot create even a single program without
writing class
c++ support got statement.
java does not support got statement.

Answer / afreen
Differences between c++ and java are as follows:-
..c++ has header file #include<iostream.h> whereas java has import java.io.*;
..c++ uses clrscr() and getch(), java do not.
..c++ supports destructor, whereas java do not.
..complilation and running program differs in c++ and java.
..java is platform independent and machine independent, whereas c++ is not.
..In c++,the entire program is written in one class itself whereas java can have multiple classes.

Answer / gurpreet singh
1.C++ supports pointers whereas Java does not pointers. But
when many programmers questioned how you can work without
pointers, the promoters began saying "Restricted pointers.”
So we can say java supports Restricted pointers.
2.At compilation time Java Source code converts into byte
code .The interpreter execute this byte code at run time
and gives output .Java is interpreted for the most part and
hence platform independent. C++ run and compile using
compiler which converts source code into machine level
languages so c++ is plate from dependents
3.Java is platform independent language but c++ is depends
upon operating system machine etc.
4.Java uses compiler and interpreter both and in c++ their
is only compiler
5.C++ supports operator overloading multiple inheritance but
java does not.
6.C++ is more nearer to hardware then Java
7.Everything is an object in Java (Single root hierarchy as
everything gets derived from java.lang.Object).
8.Java does is a similar to C++ but not have all the
complicated aspects of C++ (ex: Pointers, templates, unions,
operator overloading, structures etc..)
>>Java does not support conditional compile (#ifdef/#ifndef
type).
9.Thread support is built-in Java but not in C++.
10.Internet support is built-in Java but not in C++.
11.Java does not support header file, include library files
just like C++ .Java use import to include different Classes
and methods.
12.Java does not support default arguments like C++.
13.There is no scope resolution operator “:: “in Java.
14.There is no "goto " statement in Java.
15.Exception and Auto Garbage Collector handling in Java is
different because there are no destructors into Java.
16.Java has method overloading, but no operator overloading
just like c++.
17.The String class does use the + and += operators to
concatenate strings and String expressions use automatic
type conversion,
18.Java support call by value only.
19.Java does not support unsigned integer.
