我有这段代码:
package com.butoane;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class App {
private JButton apasaAiciButton;
private JPanel Dunno;
private JButton apoiaici;
private JTextArea text1;
public App() {
String a = "H";
String b = "e";
apasaAiciButton.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
apoiaici.setEnabled(true);
apasaAiciButton.setEnabled(false);
text1.setText(toString(a));
}
});
apoiaici.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
apoiaici.setEnabled(false);
apasaAiciButton.setEnabled(true);
apasaAiciButton.setText("Apasa iar aici");
text1.setText(toString(b));
}
});
}
public static void main(String[] args) {
JFrame frame = new JFrame("App");
frame.setContentPane(new App().Dunno);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.pack();
frame.setVisible(true);
}
}

我想要做的是,当按下一个按钮时,文本字段得到H或E,如:Button1(apasaAici)被按下,文本得到H
按下Button2(apoiAici),文本区域在" H"之后得到一个E,并且,一遍又一遍地执行此操作,textarea每次获得HeHeHeHe
,你得到它吗? / p>
我怎样才能做到这一点?
