public class ThreadDome extends Thread {
    private int    shij;
    private  int  mishu;
    public ThreadDome( int shij, int mishu) {
        super();

        this.mishu = mishu*100;
    }
    
    public void run() {

            }
            System.out.println(Thread.currentThread().getName()+"爬了"+mishu*(i+1)+"米");
        }
        System.out.println(Thread.currentThread().getName()+"到达终点");
    }

第四题：

 

 

package com.Thread;

public class qiaoDome implements Runnable {
    private  int piao = 20;   //票数
    private  int jipiao = 0;  //记录票数的


    @Override
    public void run() {
        String s = Thread.currentThread().getName();
        while(true) {
            synchronized (this) {
