superdemo.java

java经典的源代码 我非常喜欢这个源代码 对于编程很有好处

//superDemo.Java
class A
{
        int i,j;
public A(int i,int j)
{
        this.i=i;
        this.j=j;
}
int multiply(){
        return i*j;
}
} 
class B extends A
{
        int i,k;
        public B(int i,int j, int k,int l)
        {	
                super(i,j);
                this.i=l;
                this.k=k;
        }
        void show()
        {
                System.out.println("super.i="+super.i);
                System.out.println("i="+i);
                System.out.println("j="+j);
                System.out.println("k="+k);
        }
        int multiply(){
                int temp=super.multiply();
return temp*i*k;
        }
}
public class superDemo
{
        public static void main(String args[]){
                B child=new B(5,6,8,10);		
child.show();
int m=child.multiply();
System.out.println("m＝"+m);	
}
}
