2. 下面列出程序的完整实现代码：

Java示例：

package Test;

import java.awt.*;

import javax.swing.*;

import javax.swing.border.*;

public class BorderDemo {

public static void main(String[] args) {

JFrame frame = new JFrame("Swing边框演示");

frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

JPanel panel = new JPanel();

panel.setLayout(new GridLayout(0, 2, 5, 10));

panel.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));

JButton p1 = new JButton();

p1.setBorder(BorderFactory.createLineBorder(Color.red, 3));

p1.add(new JLabel("线边框"));

panel.add(p1);

JPanel p2 = new JPanel();

p2.setBorder(BorderFactory.createEtchedBorder());

p2.add(new JLabel("蚀刻边框"));

panel.add(p2);

JPanel p3 = new JPanel();

p3.setBorder(BorderFactory.createRaisedBevelBorder());

p3.add(new JLabel("斜面边框(凸)"));

panel.add(p3);

JPanel p4 = new JPanel();

p4.setBorder(BorderFactory.createLoweredBevelBorder());

p4.add(new JLabel("斜面边框(凹)"));

panel.add(p4);

JPanel p5 = new JPanel();

p5.setBorder(BorderFactory.createTitledBorder("标题"));

p5.add(new JLabel("标题边框"));

panel.add(p5);

JPanel p6 = new JPanel();

TitledBorder tb = BorderFactory.createTitledBorder("标题");

tb.setTitleJustification(TitledBorder.RIGHT);

p6.setBorder(tb);

p6.add(new JLabel("标签边框(右)"));

panel.add(p6);

JPanel p7 = new JPanel();

p7.setBorder(BorderFactory.createMatteBorder(1, 5, 1, 1, Color.yellow));

p7.add(new JLabel("花色边框"));

panel.add(p7);

JPanel p8 = new JPanel();

Border b1 = BorderFactory.createLineBorder(Color.blue, 2);

Border b2 = BorderFactory.createEtchedBorder();

p8.setBorder(BorderFactory.createCompoundBorder(b1, b2));

p8.add(new JLabel("组合边框"));

panel.add(p8);

JScrollPane scrollPane = new JScrollPane(panel);

scrollPane.setPreferredSize(new Dimension(300, 300));

frame.getContentPane().add(panel);

frame.pack();

frame.setVisible(true);

}

}

到此，Java客户端Swing程序中控件的边框定义便介绍完了，本文中，我们演示了线边框、蚀刻边框、斜面边框、标题边框、组合边框的实际用法，希望对你有所帮助。
