java的组队代码 java群组

newIT技术

JAVA小游戏的线程简单代码 (两个武士A、B对打)首先写个类命名people
public class people
{
//定义人有的属性
int blood;//血
int force;//攻击力
//定义构造方法对人进行初始化
public people(int blood,int force)
{
this.blood=blood;
this.force=force;
}
//定义人的方法，比如攻击
public void attrack(people x)
{
x.blood-=this.force;
}
}
主体中代码：
people a=new people(100,20);
people b=new people(100,30);
//建一个线程a攻击b
xiancheng one=new xiancheng(a,b);
thread t1= new Thread(one);
t1.start();
//800毫秒后建一个线程b攻击a;
thread.sleep(800);
xiancheng two=new xiancheng(b,a);
thread t2= new Thread(two);
t2.start();
class xiancheng implements runnable //继承runnable接口
{
people x;
people y;
public xiancheng(people x,people y )
{
this.x=x;
this.y=y;
}
pulbic vid run()
{
while(y.blood0)
{
x.attrack(y);
thread.sleep(800);
}
}
}
//很久没用java了线程有点忘了， ， 汗
用java ， 一共有30个人，可能包括男人，女人，小孩 。他们在一家饭馆吃饭共花了50先令，其中每个男人花了3先package test;
public class Test {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
/**
* 3x 2y z=50
* x y z=30
* 所以2x y=20
*/
for(int i=0 ;i=10;i)
{
System.out.println("男人的个数为:"i" 女人个数为："(20-2*i)" 小孩个数为："(30-i-(20-2*i)));
}
}
