Java 实例 - 线程挂起
以下实例演示了如何将线程挂起: SleepingThread.java 文件 public class SleepingThread extends Thread {
private int countDown = 5 ;
private static int threadCount = 0 ;
public SleepingThread ( ) {
super ( " " + ++ threadCount ) ;
start ( ) ;
}
public String toString ( ) {
return " # " + getName ( ) + " : " + countDown ;
}
public void run ( ) {
while ( true ) {
System . out . println ( this ) ;
if ( -- countDown == 0 )
return ;
try {
sleep ( 100 ) ;
}
catch ( InterruptedException e ) {
throw new RuntimeException ( e ) ;
}
}
}
public static void main ( String [ ] args )
throws InterruptedException {
for ( int i = 0 ; i < 5 ; i ++ )
new SleepingThread ( ) . join ( ) ;
System . out . println ( " 线程已被挂起 " ) ;
}
} |
以上代码运行输出结果为:
#1: 5
#1: 4
#1: 3
#1: 2
#1: 1
……
#5: 3
#5: 2
#5: 1
线程已被挂起
