Java vs C++ (12) 遮掩

1 Java:  不影响

class Base {

    public void test(){
        System.out.println("base test");
    }

}

public class Derived extends Base {

    public void test(int x){
        System.out.println("derived test");
    }


    /**
     * @param args
     */
    public static void main(String[] args) {

        Derived derived = new Derived();
        derived.test();

    }


}

2 C++

编译失败。

#include <iostream>
#include "Derived.h"


using namespace std;


int main() {


Derived *dervied=new Derived();
dervied->test();
delete dervied;
 }
