线程分析设计_01

练习一下,线程知识.
有一台电脑设定自动启动.我在电脑启动后就登陆qq;

设定电脑本来是关机的,然后过了3秒后就自动启动了.设计为一个线程,
class compute implements Runnable{
private boolean startwork=false;
public boolean isStartwork() {
return startwork;
}
public void setStartwork(boolean startwork) {
this.startwork = startwork;
}
public void startwork(){
startwork=true;
}
public boolean isstartwork(){
return startwork;

}
@Override
public void run() {
// TODO Auto-generated method stub

try {
Thread.sleep(3000);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
System.out.println("按啟動鍵三秒后,電腦開機了");
this.startwork();
}


}





启动后,再过5秒,我就操作电脑登陆qq.

class me implements Runnable{
compute c;
public me(compute c){
this.c=c;
}
@Override
public void run() {
// TODO Auto-generated method stub
while(!c.isStartwork()){
try {
Thread.sleep(5000);

} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
//System.out.println("我登陆qq");
denglu();
}

private void denglu(){

System.out.println("我登陆qq");
}
}




测试:先启动电脑线程,  然后我线程再启动.
public class meandcompute {

/**
* @param args
*/


public static void main(String[] args) {
// TODO Auto-generated method stub
compute c=new compute();
new Thread(c).start();
new Thread(new me(c)).start();
}

}

输出: 按啟動鍵三秒后,電腦開機了   //3秒后输出
我登陆qq               //5秒后输出
