如何在java中将文本添加到TextArea

Question

I have this code:

 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); } }

What I want to do is, when one button is pressed, the text field gets either H or E, like : Button1(apasaAici) gets pressed, the text gets H Button2(apoiAici) gets pressed, the text area gets an E after the "H", and, doing this over and over, the textarea to get every time an HeHeHeHe , you get it ?

How can I make this possible ?

Answer 1

JTextArea.append(String)

For your "H" button:

text1.append(a);

For your "e" button:

text1.append(b);
