我正在尝试使用java创建一个具有多个选项的弹出输入框，但我不知道最简单的方法是什么。目前，当我单击 GUI 中的按钮时，它会执行以下操作：
public class LoadListAction implements ActionListener{
public void actionPerformed(ActionEvent e){
Object result = JOptionPane.showInputDialog(f, "Test:");
}
}
但是，这只给了我“确定”和“取消”的选项。我想要一个弹出的框，上面有选项 1 和选项 2，并根据按下的按钮对输入框中的内容执行不同的操作。
有人可以帮忙吗？
编辑：我尝试过使用 JDialog，但似乎我无法同时获得输入框和多个可单击的按钮（或者至少我不知道如何）。
在 JDialog 中，您可以使用 add() 添加任意数量的组件！正如您在 here 中看到的，您可以使用从
ContainerComponentJDialog这是我的一个程序中的复制粘贴片段，希望您能从中有所收获：
jDialog1.setTitle("New Customer");
jDialog1.setBounds(new java.awt.Rectangle(50, 50, 1092, 638));
jLabel2.setFont(new java.awt.Font("Tahoma", 1, 14)); // NOI18N
jLabel2.setText("New Customer Details");
jLabel3.setText("Name : ");
jLabel4.setText("Address Line 1 : ");
jLabel5.setText("Address Line 2 : ");
jLabel6.setText("Address Line 3 : ");
jLabel7.setText("Phone No : ");
jLabel9.setText("Type of Customer : ");
jComboBox1.setModel(new javax.swing.DefaultComboBoxModel(new String[] { "ORDINARY", "PREVILEGED" }));
jButton6.setText("ADD CUSTOMER");
jButton6.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jButton6ActionPerformed(evt);
}
});
jButton7.setText("REFRESH");
jButton7.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jButton7ActionPerformed(evt);
}
});
jButton8.setText("CANCEL");
jButton8.addActionListener(new java.awt.event.ActionListener() {

JOptionPane 不支持你想要的，因为你有一个应该避免的令人困惑的设计。
听起来您希望用户输入“a，b，c”之类的值。然后用户将单击按钮“1、2、3”。然后对 a1, a2, a3, b1, b2, b3, c1, c2, c3 会产生不同的处理结果。
这不是一个很好的设计。相反，弹出窗口应该具有多个输入值和一个确定/取消按钮，或者一个输入值和多个可供单击的按钮。
