Java and C++ are Object Oriented Programming (OOPs) language. Java is derived from C++ , hence both has many similarities. C++ is considered more complex when compared to Java . C++ was designed for infrastructure programming and extends the C programming language. Java supports network computing.

Following are the difference between C++ and Java:

Although both are and was derived from but still there is big difference between these two languages.

  • Java does not support operator overloading
  • A class definition in Java has no closing semicolon.
  • In Java, Forward reference declarations are not required.
  • Scope resolution operator is not required in Java.
  • In C++ static data members must be re-declared outside the class
  • In C++ programming can be done without making objects.
  • Java has both compiler and Interpreter for analyzing and execution of program.
  • Java is platform Independent whereas C++ is platform dependent.
  • In C++ automatic garbage collection mechanism is absent while java has it.
  • C++ is less dynamic and more optimizable than Java.
  • C++ allows more control over compile-time optimization, whereas Java depends on the specific runtime optimization
  • C++ uses pointers while java doesn't have pointers
  • Java compiles to byte code whereas C++ compiles to machine language
  • Java has built-in Internet support while C++ does not have it.
  • C++ works on Write Once, Compile Anywhere while Java works on Write Once, Run Anywhere / Write Once, Run Everywhere.
  • C++ has multiple binary compatibility standards while Java has a binary compatibility standard
  • Java uses a package system for splitting up code in multiple source files while C++ uses a header file source code

Java is powerful, secure and safe software platform while C++ has memory leaks and it takes much development time for coding.
