[JAVA] 一个可以编辑、编译、运行Java简单文件的记事本java实现
本来是Java课做一个仿windows记事本的实验，后来突然脑子一热，结果就给它加了一个编译运行Java文件的功能。
本工程总共大约3000行代码，基本上把所学的java界面、文件、控件的功能都包含在内啦。除此之外俺还脑子一热给这个文本编辑器加了个可以编译运行java文件的功能，但是由于多线程还不咋滴，所以有些需要在DOS输入的java文件就无法运行啦。
现在过了一个寒假，好像有点忘了，所以拿出来研究一下，顺便写个博客，全做复习一下java啦，嘻嘻>_<!
notepad包：
1、关于对话框 ：介绍软件运行环境作者，版权声明。这里用JDialog便于生成模式窗口，用2个JButton一个是OK按钮，一个是无边框图标，用4个Jlable来显示文字（这里涉及字体颜色，字体设置）。更多介绍请看代码：（可单独运行）
1 package notepad; 2 //about 对话框 3 import java.awt.Color; 4 import java.awt.Font; 5 import java.awt.event.ActionEvent; 6 import java.awt.event.ActionListener; 7 import javax.swing.ImageIcon; 8 import javax.swing.JButton; 9 import javax.swing.JDialog; 10 import javax.swing.JFrame; 11 import javax.swing.JLabel; 12 import javax.swing.JPanel; 13 14 public class AboutDialog implements ActionListener{ 15 public JDialog Dialog; 16 public JButton OK,Icon; 17 public JLabel Name,Version,Author,Java; 18 public JPanel Panel; 19 AboutDialog(JFrame notepad, int x, int y) {//构造函数(父窗口，x,y) 20 //实例化界面控件 21 Dialog=new JDialog(notepad,"About Notepad...",true);//用JDialog便于写出模式窗口 22 OK=new JButton("OK"); 23 Icon=new JButton(new ImageIcon("50.png")); 24 Name=new JLabel("Notepad"); 25 Version=new JLabel("Version 1.0"); 26 Java=new JLabel("JRE Version 6.0"); 27 Author=new JLabel("Copyright (c) 2013-11-30 TaoLi. No rights reserved."); 28 Panel=new JPanel();//用一个JPanel使界面显得更美观 29 Color c=new Color(0,95,191);//颜色构造函数(r,g,b) 30 //美化界面控件 31 Name.setForeground(c);//字体前景颜色 32 Version.setForeground(c); 33 Java.setForeground(c); 34 Panel.setBackground(Color.WHITE);//Panel设为白色 35 OK.setFocusable(false); 36 Dialog.setSize(280, 180);//控件设置大小 37 Dialog.setLocation(x, y);//控件设置位置 38 Dialog.setResizable(false);//大小不可变 39 Dialog.setLayout(null); 40 Panel.setLayout(null); 41 OK.addActionListener(this);//给按钮加入监听 42 Icon.setFocusable(false); 43 Icon.setBorderPainted(false);//无边框处理 44 Author.setFont(new Font(null,Font.PLAIN,11));//设置字体 45 //组合各个控件并设置各自大小 46 Panel.add(Icon);//加入托盘 47 Panel.add(Name); 48 Panel.add(Version); 49 Panel.add(Author); 50 Panel.add(Java); 51 Dialog.add(Panel);//加入主界面 52 Dialog.add(OK); 53 Panel.setBounds(0, 0, 280, 100);//Panel大小设置 54 OK.setBounds(180, 114, 72, 26);//OK大小设置 55 Name.setBounds(80, 10, 160, 20); 56 Version.setBounds(80, 27, 160, 20); 57 Author.setBounds(15, 70, 250, 20); 58 Java.setBounds(80, 44, 160, 20); 59 Icon.setBounds(16, 14, 48, 48); 60 } 61 public void actionPerformed(ActionEvent e) {//事件监听 62 Dialog.setVisible(false); 63 Dialog.dispose(); 64 } 65 public static void main(String args[]){//测试用的main函数 66 JFrame f=new JFrame(); 67 AboutDialog a=new AboutDialog(f,400,400); 68 a.Dialog.setVisible(true); 69 } 70 }
2、颜色选择对话框： 主要为主窗口的文字的前景和背景颜色设置，主窗口的背景和选中时的背景颜色设置；其中第二个窗口负责选择颜色（也可直接输入RGB值）。这里窗口1上半部分主要由4个JLable用于文字显示，4个JButton用于分别功能选择，2个JTextArea用于显示效果；窗口2用了2维的按钮矩阵[16][16]来显示颜色。这里设置好的颜色值分别保存在public Color NFC,NBC,SFC,SBC;//4个颜色中，当其他函数调用时可以通过访问这些值来做相关操作；此外这里还把选择的数据保存在文件里了，刚开始初始化和数据改变都涉及文件操作。更多介绍请看代码:(可单独运行)

5、字体选择对话框：主要负责字体设置。更多介绍请看代码:(可单独运行)
1 package notepad; 2 import java.awt.Font; 3 import java.awt.GraphicsEnvironment; 4 import java.awt.List; 5 import java.awt.event.ActionEvent; 6 import java.awt.event.ActionListener; 7 import java.awt.event.ItemEvent; 8 import java.awt.event.ItemListener; 9 import java.awt.event.WindowEvent; 10 import java.awt.event.WindowListener; 11 import java.io.RandomAccessFile; 12 13 import javax.swing.JButton; 14 import javax.swing.JCheckBox; 15 import javax.swing.JDialog; 16 import javax.swing.JFrame; 17 import javax.swing.JTextArea; 18 19 public class FontDialog implements ItemListener, ActionListener, WindowListener{ 20 public JDialog Dialog; 21 public JCheckBox Bold,Italic;//2个CheckBox用于选择粗细和倾斜 22 public List Size,Name;//2个list用于列出字型和大小 23 public int FontName; 24 public int FontStyle; 25 public int FontSize; 26 public JButton OK,Cancel;//2个按钮 27 public JTextArea Text;//1个文本编辑区 28 private RandomAccessFile file;//存储字体文件 29 FontDialog(JFrame notepad, int x, int y){//构造函数 30 GraphicsEnvironment g=GraphicsEnvironment.getLocalGraphicsEnvironment(); 31 String name[]=g.getAvailableFontFamilyNames();//获得系统字体 32 Bold=new JCheckBox("Bold",false);//粗细倾斜设为false 33 Italic=new JCheckBox("Italic",false); 34 Dialog=new JDialog(notepad,"Font...",true); 35 Text=new JTextArea("字体预览用例\n9876543210\nAaBbCcXxYyZz"); 36 OK=new JButton("OK"); 37 Cancel=new JButton("Cancel"); 38 Size=new List();//实例化字形和大小列表 39 Name=new List(); 40 int i=0; 41 Name.add("Default Value"); 42 for(i=0;i<name.length;i++) Name.add(name[i]);//名字加进list 43 for(i=8;i<257;i++) Size.add(String.valueOf(i));//把字体加进list 44 try {//初始化信息,从保存文件读取 45 file=new RandomAccessFile("D:\\fontData.txt","rw"); 46 if(file.length()!=0){ 47 FontName=file.readInt(); 48 FontStyle=file.readInt(); 49 FontSize=file.readInt(); 50 }else{ 51 FontName=0; 52 FontStyle=0; 53 FontSize=0; 54 } 55 if(file!=null)file.close(); 56 //System.out.print(file.readInt()+" "); 57 //System.out.print(file.readInt()+" "); 58 //System.out.print(file.readInt()+" "); 59 } catch (Exception e) { 60 e.printStackTrace(); 61 } 62 Dialog.setLayout(null); 63 Dialog.setLocation(x, y); 64 Dialog.setSize(480, 306); 65 Dialog.setResizable(false); 66 OK.setFocusable(false); 67 Cancel.setFocusable(false); 68 Bold.setFocusable(false); 69 Bold.setSelected(FontStyle%2==1); 70 Italic.setFocusable(false); 71 Italic.setSelected(FontStyle/2==1); 72 Name.setFocusable(false); 73 Size.setFocusable(false); 74 Name.setBounds(10, 10, 212, 259); 75 Dialog.add(Name); 76 Bold.setBounds(314, 10, 64, 22); 77 Dialog.add(Bold); 78 Italic.setBounds(388, 10, 64, 22); 79 Dialog.add(Italic); 80 Size.setBounds(232, 10, 64, 259); 81 Dialog.add(Size); 82 Text.setBounds(306, 40, 157, 157); 83 Dialog.add(Text); 84 OK.setBounds(306, 243, 74, 26); 85 Dialog.add(OK); 86 Cancel.setBounds(390, 243, 74, 26); 87 Dialog.add(Cancel); 88 Name.select(FontName);//初始化列表选择!!!!

6、MenuList类：负责把menu的各个功能集成到这个类中单独处理，这样很方便对menu进行扩展（这里只是各个元件的组合，其监听实现不在这里，不能单独运行出现界面）

7、 TextArea类：主要的文本编辑区类，同时集成上面的menu类，基本构成该软件的主要界面和功能的封装。把menu的监听函数需要用的函数封装了一下。具体请看代码，不能单独运行出现界面：
