JPanel可以作为中间容器，组合多个组件来进行布局。可以设置该JPanel的边框和标题，程序如下：

import javax.swing.*;
import javax.swing.border.EtchedBorder;
import javax.swing.border.TitledBorder;

public class Panel1 {

	public static void main(String[] args) {
		//创建window容器
		JFrame jf = new JFrame("测试JPanel");
		//创建panel容器
		JPanel jPanel = new JPanel();
		//设置panel的边框和标题
		jPanel.setBorder(new TitledBorder(new EtchedBorder(), "按钮设置"));
		//panel组合组件
		JButton btn1=new JButton("按钮1");
		JButton btn2=new JButton("按钮2");
		jPanel.add(btn1);
		jPanel.add(btn2);
		//window中添加panel
		jf.add(jPanel);
		jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		jf.pack();
		jf.setVisible(true);
	}
}

结果如下：
