What is the difference between C++ & Java?
Answer Posted / 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.
