Although both are object oriented programming language and Java was derived from C++ but still there is big difference between these two languages.
You can see the actual difference once you start programming on it.
But here i am going to give you few differences between these two...
Java does not support operator overloading
A class definition in Java looks similar to a class definition in C++, but there is no closing semicolon.
Forward reference declarations are not required in Java.
Scope resolution operator (::) required in C++ is but not in Java.
In C++ you have to re-declare static data members outside the class but such things are not required in Java.
java does not use destructor.
If you are facing any programming issue, such as compilation errors or not able to find the code you are looking for.
