Java实现在不同线程中运行的代码实例

本文实例讲述了java实现在不同线程中运行的代码。分享给大家供大家参考，具体如下：

start()方法开始为一个线程分配cpu时间，这导致对run()方法的调用。

代码1

package threads;
/**
 * created by frank
 */
public class threadsdemo1 extends thread {
 private string msg;
 private int count;
 public threadsdemo1(final string msg, int n) {
  this.msg = msg;
  count = n;
  setname(msg + " runner thread");
 }
 public void run() {
  while (count-- > 0) {
   system.out.println(msg);
   try {
    thread.sleep(100);
   } catch (interruptedexception e) {
    return;
   }
  }
  system.out.println(msg + " all done.");
 }
 public static void main(string[] args) {
  new threadsdemo1("hello from x", 10).start();
  new threadsdemo1("hello from y", 15).start();
 }
}

代码2：

package threads;
/**
 * created by frank
 */
public class threadsdemo2 implements runnable {
 private string msg;
 private thread t;
 private int count;
 public static void main(string[] args) {
  new threadsdemo2("hello from x", 10);
  new threadsdemo2("hello from y", 15);
 }
 public threadsdemo2(string m, int n) {
  this.msg = m;
  count = n;
  t = new thread(this);
  t.setname(msg + "runner thread");
  t.start();
 }
 public void run() {
  while (count-- > 0) {
   system.out.println(msg);
   try {
    thread.sleep(100);
   } catch (interruptedexception e) {
    return;
   }
  }
  system.out.println(msg + " all done.");
 }
}

代码3：

package threads;
/**
 * created by frank
 */
public class threadsdemo3 {
 private int count;
 public static void main(string[] args) {
  new threadsdemo3("hello from x", 10);
  new threadsdemo3("hello from y", 15);
 }
 public threadsdemo3(final string msg, int n) {
  this.count = n;
  thread t = new thread(new runnable() {
   public void run() {
    while (count-- > 0) {
     system.out.println(msg);
     try {
      thread.sleep(100);
     } catch (interruptedexception e) {
      return;
     }
    }
    system.out.println(msg + " all done.");
   }
  });
  t.setname(msg + " runner thread");
  t.start();
 }
}

运行结果如下：

希望本文所述对大家java程序设计有所帮助。
