各位前辈能帮我解释下哪里错了吗?谢谢!分不多!
--------------------------------------------------
下面为代码
--------------------------------------------------
import java.awt.*;
import javax.swing.*;
import java.util.*;
public class Headlines extends JFrame{
HeadlinePanel news=new HeadlinePanel();
public Headlines(){
super( "Headlines ");
setSize(420,100);
JPanel pane=new JPanel();
pane.setLayout(new GridLayout(1,1,15,15) );
pane.add(news);
setContentPane(pane);
pane.show();
news.scroll();
}
public static void main(String[] args){
Headlines head =new Headlines();
}
}
class HeadlinePanel extends JPanel{
String[] headlines={
"000000000000000000000 ",
"111111111111111111111111 ",
"22222222222222222222222222 ",
"33333333333333333333333333333 "
};
int y=76;
void scroll(){
while(true){
y=y-1;
if(y <75)
y=76;
repaint();
try{
Thread.sleep(250);
}catch(InterruptedException e){}
}
}
public void paintComponent(Graphics comp){
Graphics2D comp2D=(Graphics2D)comp;
Font type=new Font( "serif ",Font.BOLD,14);
comp2D.setFont(type);
comp2D.setColor(getBackground());
comp2D.fillRect(0,0,getSize().width,getSize().height);
comp2D.setColor(Color.black);
for(int i=0;i <headlines.length;i++)
comp2D.drawString(headlines[i],5,y+(20*i));
}
}

应该是paintComponent
改成paintComponents吧
