import javax.swing.*;
import java.awt.*;
import java.awt.geom.*;

public class MainFrame
{
public static void main(String[] args)
{
InitFrame frame = new InitFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.show();
}
}

class InitPane extends JPanel
{
public void paintComponent(Graphics g)
{
super.paintComponent(g);
g.drawString("一生平安",WIDTH,HEIGHT);
g.drawRect(100,100,100,80);
}
private static final int WIDTH=50;
private static final int HEIGHT=50;
}
class InitFrame extends JFrame
{
public InitFrame()
{
setTitle("ok");
setSize(WID,HEI);
InitPane pane =new InitPane();
Container contentpane = getContentPane();
contentpane.add(pane);
}
private static final int WID=500;
private static final int HEI=500;
}
结果就提示如下了
C:\pro>javac MainFrame.java
Note: MainFrame.java uses or overrides a deprecated API.
Note: Recompile with -Xlint:deprecation for details.
我真是不知道该如何了？才请教大家的啊[:(]

Posted by: why Posted on: 2005-05-18 00:27 search for the meaning of deprecated and its implications. Disable Simlies and the 礼物 will display as (g) http://java.sun.com/j2se/1.4.2/docs/api/java/awt/Component.html#show() public void show() Deprecated. As of JDK version 1.1, replaced by setVisible(boolean).
