Difference between C++ and Java

The main difference between c++ and java is that java is consistent and it is a dynamic model.it is compact and portable binary code while c++ is not. and most important difference is the it has safe and secure execution environment.
The main purpose to developed java language is that "TO MAKE UNIQUE COMPILER".
java have unique compiler and c++ have savral compiler.
C++                                                                                    java


pointers                                                                            no pointers
multiple inheritance                                                           multiple inheritence with interface
platform dependent                                                          plotformindependent
goto keyword.                                                                 doesnot contain goto keyword.


enum, struct,union                                                            doesn't contain any data types such as
                                                                                       enum, struct,union.
predessor                                                                        does not support predessor
operatoroverloading                                                        does not support operator
                                                                                       overloading(using multithreading capability)
