❶ java多线程--模拟接力赛跑

import java.util.*;

public class Main {
public static void main(String[] args) {
RunThread run = new RunThread();
for (int i = 1; i <= 5; ++i) {
new Thread(run, i + "号选手").start();
}
}
}

class RunThread implements Runnable {
int distance;

@Override
public synchronized void run() {
String name = Thread.currentThread().getName();
System.out.println(name + "拿到接力棒！");
for (int i = 0; i < 10; ++i) {
distance += 10;
System.out.println(name + "跑到了" + distance + "米!");
}
}

}

❸ java课程设计 模拟游乐场的投篮游戏 求帮忙

没有玩过游乐场的投篮游戏

❹ 用java设计一个具有时钟和适用于篮球比赛倒计时的界面,并不要求有实际功能。~~~大大们求代码~~~

一分不给，太抠门了这也

❺ java项目类似篮球的比赛投屏要使用socket

socket只是一个协议，简历连接以后，一端把流发出去，另一端的接收端口就会收到，所以你知道简单学习一下socket怎么发送就可以了，而且你这个项目不需要多线程，所以不会有大问题

❻ JAVA编程题中，四个学生小李,小张,小赵,和小王在打篮球,现在编写一个程序,模拟他们抢篮球的过程,

ご参照してください。
public class People {

private String name;
public int num;
public People(String name) {
this.name = name;
this.num = 0;
}

public String getName() {
return this.name;
}
}
--------------------------------------------------------------------------------------------------
public class Play {

public static void main(String[] args) {

Play play = new Play();

List<People> pl = new ArrayList<People>();
pl.add(new People("小王"));
pl.add(new People("小张"));
pl.add(new People("小赵"));
pl.add(new People("小李"));
while(pl.size() > 0) {
play.challenge(pl);
}
}

private void challenge(List<People> pl) {
Random rd = new Random();
// この人はリストにのインデックス。リストは人がひとつある场合、ゼロです。
int nowPeople = pl.size() > 0 ? rd.nextInt(pl.size()) : 0;
int total = pl.get(nowPeople).num + 1;
pl.get(nowPeople).num = total;
System.out.println(pl.get(nowPeople).getName() + "抢到了，第" + total + "次球");
// 何番目でアウトする
if (total == 7) {
System.out.println(pl.get(nowPeople).getName() + "不想玩了");
pl.remove(nowPeople);
}
}

}

❼ 用JAVA写一个有关世界杯淘汰赛赛程的程序

付费还差不多- -。。。。。

❽ 模拟队伍比赛 JAVA

不想写代码 给你个思路，首先要确定怎么来确定晋级，比多少次 应该是n-1次，
确定淘汰 就是用取0--1之间的随机数 如甲乙实力比是1/2 那么产生随机数 0-1之间的 分为3份 可以当产生0-1/3 时 甲晋级 否则乙晋级 可以满足 淘汰实力对比，
其余的应该都不是难点啊
随机函数在 Math类中
具体自己研究吧

❾ 用Java语言建立一个学生打篮球的模型

二语言可以干很多事情，你可以直接下载一个作业帮，然后输入你的问题就可以出来解释了
