ta.setForeground(Color.black);//設置文本顏色

ta.addKeyListener(new KeyAdapter() {

s+=ev.getKeyChar();

}

});

f.setSize(400,200);

f.setVisible(true);

menuListener=new MenuListener();

mExit.addActionListener(menuListener);

mOpen.addActionListener(menuListener);

mSave.addActionListener(menuListener);

f.addWindowListener(new WindowAdapter() {

public void windowClosing(WindowEvent e) {

System.exit(1);

}

});

}

public static void main(String[] args) {

TextEditor te=new TextEditor();

}

class MenuListener implements ActionListener{

public void actionPerformed(ActionEvent ev) {

MenuItem i=(MenuItem)ev.getSource();

String label=i.getLabel();

if(label=="退出") System.exit(1);

else if(label=="保存") saveFile();

}

}

void saveFile() {

fd=new FileDialog(f,"請輸入要保存的文件名",FileDialog.SAVE);

fd.setVisible(true);

fileName=fd.getFile();

try {

fos=new FileOutputStream(fileName);

osw=new OutputStreamWriter(fos);

System.out.println(s);

osw.write(s);

osw.flush();

osw.close();

fos.close();

}catch(Exception e) {}

}

}

運行之后，可以看到中文亂碼，如圖所示：
