java 实现多重继承

package com.yangll;

//多重继承类
public class ClassTestylll extends Person1 {

class inner extends Machine1{
@Override
void run() {
// TODO Auto-generated method stub
System.out.println("Machine1 is run");
}
}

public void run1(){
this.run();
}
public void run2(){

public void run3(ClassTestylll a){

}

public inner getInner(){

t.run3(t);
t.run4(t.getInner());
}
}

class Person1{
public void run(){System.out.println("Persion1 is run");};
}

abstract class Machine1{
