java编写简单记事本
方法/步骤
下载JDK，并安装成功，CMD测试Java环境安装成功。出现如下提示则Java环境安装成功
打开mycelipse进入主界面，点击左上角file--new---java project,新建一个Java项目，项目名字任意取，这里我取名为note--然后点击完成，创建Java项目
然后右键项目下的src--new---package,新建一个包，包名我定为notetest，然后点击完成
然后右键我们建立好的包notetest--new--class，包名为Note,点击完成
首先我们想导入工程所需要的包，以便编写程序时进行调用
package notepad;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.io.BufferedReader;
import java.io.BufferedWriter;
首先定义好编写程序时变量，我们设为成员变量方便以后调用
public class Notepad{
//屏幕分辨率
int width = Toolkit.getDefaultToolkit().getScreenSize().width;
int height = Toolkit.getDefaultToolkit().getScreenSize().height;
//窗体
private Frame frm ;
//显示内容多行文本
private TextArea notetext;
//记事本菜单
private MenuBar mb;
//菜单
private Menu m ;
//菜单项
private MenuItem open,save;
为程序创建组件--Frame--菜单栏目--文本框TextArea
public Notepad(){init();}
private void init(){
frm = new Frame("模拟记事本");
//设置菜单
mb = new MenuBar();
m = new Menu("文件");
//显示文件的地方
notetext = new TextArea();
notetext.setBounds(30, 50, 750, 500);
frm.add(notetext);
myEvent();
为控件和按钮添加监听事件
private void myEvent() {
//打开菜单的事件处理
open.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//判断路径和文件名是否为空 如果为空结束程序
if(dir == null || name == null)
//如果不为空讲路径名和文件名封装到File对象里
file = new File(dir,name);
//使用字符缓冲读取文件
BufferedReader bfr = null;
try {
bfr = new BufferedReader(new FileReader(file));
});
save.addActionListener(new ActionListener(){
//获取路径和文件名
String dir =fd.getDirectory();
String name = fd.getFile();
//如果不为空讲路径名和文件名封装到File对象里
file = new File(dir,name);
}
BufferedWriter bfr= null;
}
});
}
}
然后创建主方法，开始测试程序，新建一个NoteDemo类
package notepad;
public class NoteDemo {
public static void main(String[] args) {
new Notepad();
}
}

如何用java一步步编出一个记事本程序
一、要创建一个Frame或者JFrame现在基本上都用后者
二、要建立你的控件，就是面板Jpanel菜单JMenu\JMenuItem等，写字板textArea等，
三、动作监听器，addActionListener
四、就是你的布局了
一下是一个可以运行的，你看看
