Java2入门经典教程 11.1 了解线程[3]

试试看派生Thread的子类

用一个例子我们可以看到这是如何工作的我们将定义一个由Thread的类派生的类TryThread执行从main（）方法开始

import javaioTOException;

public java TryThread extends thread

{

private string firstName; //store for first name

private string secondName; //store for second name

private long awhile //Delay in milliseconds

public TryThread(string firsNamestring secondName long delay

{

thisfirstName=firstName //store the first name

thissecondName=secondName; //store the second name

awhile=delay //store the delay

setDaemon(true) //Thread is daemon

}

public static void main (string[]args)

{

//create three threads

Thread first =new TryThread(HopalongcassidyL);

Thread second=new TryThread(MarilynMonroeL);

Thread third =new TryThread(slimpickensL);

systemoutprintln(press Enter when you have had enough\n);

firststart(); //start the first thread

secondstart(); //start the second thread

thridstart(); //start the thrid thread

try

{

systeminread(); //wait until Enter key pressed

systemoutprintln(Enter prosed\n);

}

catch (IOException e) //Hand Io exception

{

systemoutprintln(e); //Output the exception

}

systemoutprintln(Ending main());

return;

//Method where thread execption will stare

public void run()

{

try

{

while(ture) //Loop indefinitely

{

systemoutprin(firstName); //output first name

sleep(awhile); //wait awhile mses

systemoutprint(secondName + \n); //output second name

}

}

catch(InteruptedException e) //Hand thread interruption

{

systemoutprintln(firstName+secondName+e); //Output the exception

}

}

}
