There are many differences between C++ & Java programming language.
·
Platform-independent : C++ is platform-dependent but Java is platform-independent.
·
Mainly used for : C++ is mainly used for system programming but Java is
mainly used for application programming.
·
Design Goal : C++ was designed for systems and applications programming but
Java was designed and created as an interpreter for printing systems.
·
Goto : C++ supports the goto statement but Java doesn't support the goto
statement.
·
Multiple inheritance : C++ supports multiple inheritance but Java doesn't support
multiple inheritance through class.
·
Operator Overloading : C++ supports operator overloading but Java doesn't support operator overloading.
·
Pointers : C++ supports pointers.You can write pointer program in C++ but Java supports
pointer internally.since, you can't write the pointer program in java.
· Compiler and Interpreter : C++ uses compiler only but Java uses compiler and interpreter both.
·
Call by Value & Call
by reference : C++ supports both call by value & call by
reference but Java supports call by value only.
·
Structure & Union : C++ supports structures & unions but Java doesn't
support structures & unions.
·
Thread Support : C++ doesn't have built-in threads support but Java has
built-in thread support.
·
Documentation comment : C++ doesn't support documentation comment but Java supports
documentation comment (/** ... */).
·
Virtual Keyword : C++ supports virtual keyword but Java doesn’t supports virtual keyword.
·
unsigned right shift >>> : C++ doesn't
support unsigned right shift >>> operator but Java supports unsigned
right shift >>> operator.
·
Inheritance Tree : C++ creates a new inheritance tree always but Java uses a
single inheritance tree always.
·
Hardware : C++ is interact with hardware but Java is not interact with
hardware.
·
Object-oriented : C++ is an object-oriented programming language but Java is
also an object-oriented programming
language.
Ø Note : C++ is compiled and run using the compiler which converts source code into machine code but Java source code is converted into bytecode at compilation time and The interpreter executes this bytecode at runtime and produces output.
