java看看我是怎么利用数组给Runnable线程传参数的1

我的文章只给有耐心的人看，所以先写代码

import java.util.concurrent.ExecutorService;

import java.util.concurrent.Executors;
import java.util.concurrent.Semaphore;

public class TestWait implements Runnable {
//   当前信号量
   int nt = 0;
//   线程池
   ExecutorService service = null;
//   全局信号量
   Semaphore sp = null;


   public ExecutorService getService() {
       return service;
   }

   public void setService(ExecutorService service) {
       this.service = service;
   }

   public Semaphore getSp() {
       return sp;
   }

   public void setSp(Semaphore sp) {
       this.sp = sp;
   }

   public int getNt() {
       return nt;
   }

   public void setNt(int nt) {
       this.nt = nt;
   }

   public static void main(String[] args) {
//       线程池
       ExecutorService tservice = Executors.newCachedThreadPool();
//       设定多线程并发信号量
       final Semaphore tsp = new Semaphore(10);

       int cnt = 100;
       for (int i = 1; i <= cnt; i++) {

           System.out.println("add the No. [" + i + "] thread in thread serveice!");
           //Test t = new Test();
           TestWait t = new TestWait();
           t.setNt(i);
           t.setService(tservice);
           t.setSp(tsp);

           Thread td = new Thread(t);

           tservice.execute(td);

       }
       tservice.shutdown();
   }

   public void run() {
       try{
//           线程加数
           sp.acquire();
       }
       catch(Exception e)
       {
           e.printStackTrace();
       }

           System.out.println("--------->thread No. [" + nt + "] start ! ***** 还有 " +sp.getQueueLength()+" 线程等待执行");


           try {
               Thread.sleep(2000);//9000); //1000);
           } catch (InterruptedException e1) {
               e1.printStackTrace();
           }

       try{
//           线程减数
           sp.release();
       }catch(Exception e)
       {
           e.printStackTrace();
       }

   }

}

问题来源于给Runnable 接口的线程传参数……

多个线程，传进去的参数全不一样……

比如进去的、出来的……

先看个（游戏）参与者类：

public class Playe2r {

public    int id;
//   String name;
   int state; //1 可以对弈

   public Playe2r( int i, int j) {
       id=i;
       //name=nam1e;
       state=j;
       // TODO Auto-generated constructor stub
   }
   void setId(int i1d ) { this.id= i1d;}
   int getId() {return this.id;}
}

import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;

public class player1test1 {

   public static void main(String[] args)
   {
       Playe1r p1[]=new Playe1r[1000];
       for(int i=0;i<p1.length; ++i) {
           p1[i]=new Playe1r(i,""+i+"",1);
//           p1[i].setId(i);
           p1[i].id=i;
           p1[i].state=(int) (9*Math.random());
       }

       for(int i= (p1.length-1); i>0; --i) {
           p1[i].getId();
           System.out.print(p1[i].id);
           System.out.print(":");
           System.out.println(p1[i].state);
       }
       System.out.println();

       //--
       List lst1=new ArrayList();

       for(int i1=0;i1<p1.length;++i1) {
           if( (1<p1[i1].state )&&(4>p1[i1].state) ) {
               lst1.add( new Playe2r(p1[i1].getId(), p1[i1].state) );
           }//if(1==p1[i1].getId(i1
       }//for(int i1

       Iterator it = lst1.iterator();
       while(it.hasNext()){
          // String s = (String)it.next(). ;
           Object obj=it.next();
           Playe2r objj=(Playe2r) obj;
           System.out.print(objj.getId() );
           System.out.print(" ");
           System.out.println(objj.state);
       }

       //==

       //-某player1 发起邀请

       for (int i1i=1;i1i<99;++i1i) {
           int rami=lst1.size();
           int no_i=(int) (rami*(Math.random()));

           for (int j1=1;j1<rami;++j1) {
               if (no_i!=j1) {
                   //把 (no_i, j1) 这两个参数分别传给邀请的 TestWait 线程（编号为响应的线程池中的线程……
               }//if (no_i!=j1
           }//for(int j1=1

       }//for int i1i=1

       //==


   }//main

}//class player1test1

主要的程序就是以上的部分……

至于利用 “数组”如何传相应（编号）的参数进去，咱们下回再说（文章已经够长了……）
