我的程序编译有问题,请帮忙改正!
import java.awt.*;
import java.applet.*;
import java.util.Date;
public class Clock extends Applet implements Runnable
{
Thread clockThread;
Font font;
public void init()
{
font =new Font( "TmesRoman ",Font.BOLD,48);
}
public void start()
{
if(clockThread==null)
{
clockThread=new Thread(this, "Showtime ");
clockThread.start();
}
}
public void run()
{
while(clockThread!=null)
{
repaint();
try
{
clockThread.sleep(1000);
}catch(InterruptedException e) { }
}
}
public void paint(Graphics g)
{
Date now =new Date();
g.setFont(font);
g.setColor(Color.red);
g.drawString(now.getHours()+ ": "+now.getMinutes()+ ": "+now.getSeconds(),5,50);
}
public void stop()
{
clockThread.stop();
}
}
编译结果:
D:\xu> javac Clock.java
Note: Clock.java uses or overrides a deprecated API.
Note: Recompile with -deprecation for details.
------解决方案--------------------clockThread.stop();
去掉
这个方法deprecated
