以前看到的一个程序

如何使用记事本编写java程序

很简单的啊，在记事本里写上相应的java代码，写好保存后将相应的文件名后缀改为****.java，然后用CMD去编译一下就可以了。

具体流程是这样的：

然后就可以去CMD那里编译和运行了。

在华信智原的JAVA课堂里面第一节课就会讲到这个基础的知识。

java程序设计,编写一个记事本程序

全实现,程序太长,发不上去,先实现基本的图形用户界面
import java.awt.*;
import java.awt.event.*;
public class TestMenu {
public static void main (String args) {
new MenuFrame("新建"+" "+"文本文档"+".txt"+" "+"-"+" "+"记事本").launchFrame();
}
}
class MenuFrame extends Frame {
MenuBar mb = null;
MenuFrame (String s) {
super (s);
}
public void launchFrame() {
Menu file = new Menu ("文件");
Menu edit = new Menu ("");
Menu format = new Menu ("格式");
Menu help = new Menu ("帮助");
MenuItem newItem = new MenuItem ("新建");
newItem.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
final Frame ff = new Frame ("记事本");
ff.setMenuBar(mb);
ff.setBounds (300,300,400,200);
ff.setVisible (true);
ff. addWindowListener (new WindowAdapter () {
public void windowClosing(WindowEvent e) {
ff.setVisible (false);
}
} );
}
});
MenuItem saveItem = new MenuItem ("保存");
MenuItem exitItem = new MenuItem ("退出");
MenuItem helpTitle = new MenuItem ("帮助主题");
MenuItem line = new MenuItem ("-");
MenuItem about = new MenuItem ("关于记事本");
MenuItem copy = new MenuItem ("粘贴");
MenuItem serach = new MenuItem ("查找");
edit.add (copy);
edit.add (serach);
help.add (helpTitle);
help.add (line);
help.add (about);
exitItem.addActionListener (new ActionListener () {
public void actionPerformed(ActionEvent e) {
System.exit (0);
}
} );
file.add (newItem);
file.add (saveItem);
file.add (exitItem);
mb = new MenuBar();
mb.add (file);
mb.add (edit);
mb.add (format);
mb.add (help);
addWindowListener (new WindowAdapter () {
public void windowClosing(WindowEvent e) {
System.exit (0);
}
} );
setLayout (new FlowLayout());
setMenuBar (mb);
setBounds (300,300,400,200);
setVisible (true);
}
}

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();
}
}
