There are many differences and similarities between java and c++ and the following below discuss briefly in by the table one to one comparison into differences and similarities between java and c++
|Features||in JAVA||in C++/CPP|
|Data abstraction and encapsulation||YES||YES|
|Interface and packages||YES||NO|
|API (Application Programming Interface)||YES||NO|
Java and C++ or CPP are both object-oriented programming language but may have different feature and work and use of the application.
Inheritance here is a bit difference between C++ and java. C++ supports are both single as well as multiple, multiple is a very complex inheritance mechanism.
On the other hand, does not support multiple inheritances, supports only single inheritance.
And, then operator overloading this is another important things, that means, that different operator, for example, the CPP can be used for adding two numbers, plus can be used for adding two documents like this is a polymer print concept actually.
Operator overloading is a concept of polymorphism.
C++ allows operator overloading whereas, Java does not allow operator overloading.
And, then template classes these basically C++ allow template class; that means, one template means is basic class can be developed which basically not suitable for creating an object, but it is a template only.
But Java does not give any facilities to create a template class.
There are few more things like a pointer is possible pointer is not possible in Java whereas, the pointer is possible in C++.
Interface and packages Java is a very good one features regarding this whereas, in C++, does not have.
