示例
package my;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Container;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.border.LineBorder;
import javax.swing.border.TitledBorder;
public class SwingDemo {
public static void main(String args[]) {
JFrame frame = new JFrame("Demo");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
LineBorder linedBorder = new LineBorder(Color.YELLOW);
TitledBorder titledBorder = BorderFactory.createTitledBorder(linedBorder, "Demo Title");
titledBorder.setTitleJustification(TitledBorder.LEFT);
JLabel label = new JLabel();
label.setBorder(titledBorder);
Container contentPane = frame.getContentPane();
contentPane.add(label, BorderLayout.CENTER);
frame.setSize(550, 300);
frame.setVisible(true);
}
}
