Java多线程的线程类需继承于Thread类，并且需要重写run函数。
sleep休眠时使用Thread.sleep( 200 )这种形式，并且要放在try-catch语句块中。
下面给出简单demo：
class MyThread extends Thread
{
public MyThread( String
strName0 )
{
super( strName0 );
}
public void
run()
{
for( int i=0; i<10; ++i
)
{
System.out.println( "Thread name is: " +
this.getName()
);
try
{
Thread.sleep(300);
}
catch(
InterruptedException e )
{
System.out.println(
e.getMessage() );
}
}
}
}
public class TestMultiThread
{
public static void main(String[] args)
{
MyThread
thread1 = new MyThread( "ThreadA" );
MyThread thread2 = new
MyThread( "ThreadB" );
//MyThread thread3 = new MyThread(
"ThreadC"
);
thread1.start();
thread2.start();
//thread3.start();
}
}
