difference between java,c++

1. there is not destructive method in java
2. there is not default parameter in java's method.
3. class declaration :  java : has public or private before class,
4. inheritance :  java extends , c++ :public --- java only has pulic inheritance. default class member is public member.
5. to method , public statement for a single method in java,  public statement for a block in c++ (because no .h file.)
6. in java declaration & define in one file, in c++ declaration & define can be in seperate files (such as .cpp .h)
7. interface in java can extends(between interface

8. java use interface & inner class to implement multiple inherientence.

9. in java , child class cannot  make parents' method invisible, in c++ this is ok.

such as :

in java below will compile error:

public class parent{
    public void print() {System.out.println("parent print");}
}

public class child extends parent{
    private void print() {System.out.println("child print");}
}

in c++ below is ok

class parent{
    public:

 void print() {System.out.println("parent print");}
}

class child : public parent{
    private:

 void print() {System.out.println("child  print");}
}

10.  static method

Class A{

class B ｛

static void test(){}

｝

}

in c++: ok

in java: compile error,

java static method must at static , or the top class.
