推荐答案
简单来说，您需要向用户要单击的按钮添加一个动作侦听器.例如:该按钮将用于发布内容. "POST"
simply, you need to add an action listener to the button which the user is going to click.for example: the button will be for posting something. "POST"
public class YourProject extends JFrame implements ActionListener{
JtextField text = new JtextField();
JButton post = new JButton("POST");
public YourProject(){
add(text);
add(post);
post.addactionlistener(this);
setVisible(true);
}
@Override
public void actionPerformed(ActionEvent e) {
if(e.getSource()==post) {
String removed = text.getText().trim();
System.out.println(removed);
}
如果用户输入"Hello World"，然后单击发布"，则输出将为"HelloWorld".希望这会有所帮助.
If the user writes "Hello World" then clicks post, the output will be "HelloWorld".hope this helps.
