Panel details:

Panel means panel. Panel is the simplest container class in Java. Applications can place other components, including other panels, within the space provided by a panel. It is a basic component that is rarely used directly, either inherited and overridden, or used to organize other components.

Give an example about panel:

package com.awt.frame;
import java.awt.Color;
import java.awt.Frame;
import java.awt.Panel;//使用了Panel类
/**
 * 
 * @author Administrator
 *	java.lang.Object
 *		java.awt.Container
 *			java.awt.Panel
 */
public class PanelInFrame extends Frame {
 
	public static void main(String[] args) {
			PanelInFrame fr=new PanelInFrame("Frame With Panel");
			Panel pan=new Panel();
			fr.setSize(200,200); 					//设置Frame窗体大小
			fr.setBackground(Color.yellow);			//设置fr的背景颜色为黄色，默认是白色
			fr.setLayout(null); 					//取消布局管理器
			pan.setSize(100,100); 					//设置panel大小
			pan.setBackground(Color.green); 		//设置panel的背景颜色为绿色
			fr.add(pan);							//使用Add方法把panel面板添加到框架fr中
			fr.setVisible(true); 					//设置Frame可见性，默认为不可见
	}
	public PanelInFrame(String str) {
		super(str);
	}

}
