當(dāng)從form1打開(kāi)form2單擊按鈕時(shí)，我正在嘗試做。它聽(tīng)起來(lái)很簡(jiǎn)單，但我找不到任何方法來(lái)做到這一點(diǎn)。我正在使用 java intellij。當(dāng)我使用netbeans和swing時(shí)，我正在這樣做：“Form2 form2=new Form2();form2.setVisible(true);處置（）；"表格1（主要）：public class Main { private JButton b_show; private JButton b_Add; private JPanel jp_main; public Main() { b_show.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent actionEvent) { } }); } public static void main(String[]args){ JFrame frame=new JFrame(); frame.setContentPane(new Main().jp_main); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(300,300); frame.setVisible(true); }}表格2（顯示）：public class Show { private JButton b_back; public JPanel jpanelmain; public Show() { Show show=new Show(); geriButton.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent actionEvent) { } }); } public static void main(String[]args){ JFrame frame=new JFrame(); frame.setContentPane(new Show().jpanelmain); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.setSize(300,300); frame.setVisible(true); }}有人可以幫助我嗎？單擊 b_show 時(shí)打開(kāi) form2（顯示）。

這是一個(gè)演示它的mcve
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
public class Main {
private final JButton b_show;
private final JPanel jp_main;
public Main() {
jp_main = new JPanel();
b_show = new JButton("Show");
b_show.addActionListener(actionEvent -> {
new Show();
});
jp_main.add(b_show);
}
public static void main(String[]args){
JFrame frame=new JFrame();
frame.setContentPane(new Main().jp_main);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300,300);
frame.setVisible(true);
}
}
class Show {
private JButton b_back;
public JPanel jpanelmain;
public Show() {
createAndShowGui();
}
void createAndShowGui(){
JFrame frame=new JFrame();
frame.setLocationRelativeTo(null);
jpanelmain = new JPanel();
b_back = new JButton("Back");
jpanelmain.add(b_back);
frame.setContentPane(jpanelmain);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300,300);
frame.setVisible(true);
}
}

最好的方法是使用 JDialogs。在actionPerformed()調(diào)用“Form1”時(shí)，您將實(shí)例化一個(gè)新的 JDialog 并將其設(shè)置為可見(jiàn)。這是一個(gè)例子：
public class Show extends JDialog {
private JButton b_back;
public JPanel jpanelmain;
public Show(Frame owner, boolean modal) {
super(owner, modal);
}
//method that creates the GUI
}
b_show.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent actionEvent) {
Show show = new Show(JOptionPane.getFrameForComponent(this), true);
show.setVisible(true);
}
});
最后，當(dāng)你想關(guān)閉對(duì)話框時(shí)，actionPerformed()在里面實(shí)現(xiàn)一個(gè)，并調(diào)用dispose()方法
