使用java编写的LSB图像信息隐藏算法演示程序

package hideInfo;

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

//定义程序的窗口
public class HideInfoFrame extends JFrame {
  
	JPanel contentPane;   //窗口中的Panel
	
  //Construct the frame
  public HideInfoFrame() {
    enableEvents(AWTEvent.WINDOW_EVENT_MASK);   
    try { 
      jbInit();   //调用初始化窗口
    }
    catch(Exception e) {
      e.printStackTrace();
    }
  }
  //Component initialization
  private void jbInit() throws Exception  {
	  this.contentPane=new HideInfoPanel();   //建立程序Panel，panel中有着按钮等等
	  this.setSize(800,500);
	  this.contentPane.repaint();
	  this.setContentPane(this.contentPane); //把Panel和窗口联系在一起
  }
  //Overridden so we can exit when window is closed
  protected void processWindowEvent(WindowEvent e) {
    super.processWindowEvent(e);
    if (e.getID() == WindowEvent.WINDOW_CLOSING) {  //收到关闭信息则关闭窗口推出程序
      System.exit(0);
    }
  }
