Java BorderFactory

那个边框怎么设置成弧线，就是四个角别那么方，设置成弧线就可以了 
谢谢大家

答案：绘图
import java.applet.*;
import java.awt.*;
public class ko9_1 extends Applet
{
public void paint(Graphics g)
{
int x[]={0,100,100,0,0};
int y[]={0,0,100,100,0};
g.drawPolyline(x,y,5);
for (int n=0;n=0;m-=10)
{
g.drawLine(m,n,n,m);
}
g.drawString("drawLine",20,120);
}
}

对于画普通的直线border  不支持，用下面方法：
new LineBorder(Color.RED, 1, true)   true 就是圆角。
---------
创建title   border可以，不过要用上面的方法作为参数。。。
