java文本编辑器java jfilechooser 文本编辑器

麻烦高手推荐几款比较适合初学者编写JAVA程序的文本编辑器？

notepad++ //一个支持多种语言的文本编辑器，带有代码提示、语法高亮功能！ editplus //支持Java语言。

有语法高亮功能。

没有代码提示！ ultraedit //同editplus

用JAVA设计一个简单文本编辑器

import java.awt.*; import javax.swing.*; import java.awt.event.*; import javax.swing.event.*; import java.util.*; //Date needed import java.io.PrintWriter; public class NotePad extends JFrame { JTextArea jta; class newl implements ActionListener { public void actionPerformed(ActionEvent e) { jta.setText(""); } } class openl implements ActionListener { public void actionPerformed(ActionEvent e) { JFileChooser jf=new JFileChooser(); jf.showOpenDialog(NotePad.this); } } //保存文件的监听 class savel implements ActionListener { public void actionPerformed(ActionEvent e) { JFileChooser jf = new JFileChooser(); jf.showSaveDialog(NotePad.this); } } //打印的监听 ? class printl implements ActionListener { public void actionPerformed(ActionEvent e) { // PrintWriter p = new PrintWriter(NotePad.this); } } //退出记事本的监听 class exitl implements ActionListener { public void actionPerformed(ActionEvent e) { System.exit(0);//退出 } } //拷贝的监听 class copyl implements ActionListener { public void actionPerformed(ActionEvent e) { jta.copy(); } } //粘贴的监听 class pastel implements ActionListener { public void actionPerformed(ActionEvent e) { jta.paste(); } } //剪切的监听 class cutl implements ActionListener { public void actionPerformed(ActionEvent e) { jta.cut(); } } //查找的监听 //添加日期的监听 class datel implements ActionListener { public void actionPerformed(ActionEvent e) { Date d=new Date(); jta.append(d.toString()); } } //构造函数 public NotePad() { jta=new JTextArea("",24,40); JScrollPane jsp=new JScrollPane(jta); JMenuBar jmb=new JMenuBar(); JMenu mFile=new JMenu("File"); JMenu mEdit=new JMenu("Edit"); JMenuItem mNew=new JMenuItem("New",KeyEvent.VK_N); mNew.addActionListener(new newl()); mFile.add(mNew); JMenuItem mOpen=new JMenuItem("Open",KeyEvent.VK_O); mOpen.addActionListener(new openl()); mFile.add(mOpen); JMenuItem mSave=new JMenuItem("Save"); mSave.addActionListener(new savel()); mFile.add(mSave); mFile.addSeparator(); //添加分割线 JMenuItem mPrint = new JMenuItem("Print"); mPrint.addActionListener(new printl()); mFile.add(mPrint); mFile.addSeparator(); //添加分割线 JMenuItem mExit=new JMenuItem("Exit"); mExit.addActionListener(new exitl()); mFile.add(mExit); mFile.setMnemonic(KeyEvent.VK_F); //编辑菜单的子菜单的处理 JMenuItem jmi; jmi=new JMenuItem("Copy"); jmi.addActionListener(new copyl()); mEdit.add(jmi); jmi=new JMenuItem("Cut"); jmi.addActionListener(new cutl()); mEdit.add(jmi); jmi=new JMenuItem("Paste"); jmi.addActionListener(new pastel()); mEdit.add(jmi); mEdit.addSeparator(); //添加分割线 jmi=new JMenuItem("Find"); mEdit.add(jmi); jmi=new JMenuItem("FindNext"); mEdit.add(jmi); mEdit.addSeparator(); jmi=new JMenuItem("Select All"); mEdit.add(jmi); jmi=new JMenuItem("Date/Time"); jmi.addActionListener(new datel()); mEdit.add(jmi); jmb.add(mFile); jmb.add(mEdit); this.setJMenuBar(jmb); this.getContentPane().add(jsp); this.setSize(200,200); this.setVisible(true); } //主函数，程序入口点 public static void main(String s[]) { new NotePad(); } }

求java做一个文本编辑器，要求如下，缺一不可，如果可以追加悬赏100分！！

java jfilechooser 文本编辑器

保存(另存)的话还是用FileDialog吧。

写个方法，在另存为时直接调用就OK了，如下： public void saveAs() { try { FileDialog fd = new FileDialog(frame, "另存为", FileDialog.SAVE);//frame为所依附的窗体 fd.setVisible(true); FileOutputStream out = new FileOutputStream(fd.getDirectory() + fd.getFile() + ".txt");//存为.txt格式，文件名为你输入的字符串 String str = ta.getText(); for (int n = 0; n < str.length(); n++) { out.write((byte) str.charAt(n)); } out.close(); } catch (Exception ess) { } }
