我正在做一个简单的Phone book diary，所以问题是
点击new后，必须打开一个对话框JOptionPane，
是的，它成功打开，但点击ok后，我想再次显示一个新的对话框询问电话号码..我知道要编码但是找一个逻辑怎么做？
这是我的源代码：
package phonebook;
import javax.swing.*;
public class MainProgram extends javax.swing.JFrame {
public MainProgram() {
initComponents();
}
private void initComponents() {
jLabel1 = new javax.swing.JLabel();
jLabel2 = new javax.swing.JLabel();
jScrollPane1 = new javax.swing.JScrollPane();
jTable1 = new javax.swing.JTable();
jMenuBar1 = new javax.swing.JMenuBar();
jMenu1 = new javax.swing.JMenu();
jMenu2 = new javax.swing.JMenu();
jMenuItem1 = new javax.swing.JMenuItem();
jMenuItem2 = new javax.swing.JMenuItem();
jMenuItem3 = new javax.swing.JMenuItem();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Phone book made by Rajendra Arora");
jLabel1.setFont(new java.awt.Font("Segoe UI Semibold", 1, 14));
jLabel1.setHorizontalAlignment(javax.swing.SwingConstants.CENTER);
jLabel1.setText("Welcome to Phonebook diary!");
jLabel1.setToolTipText("");
jLabel2.setText("Made by: Rajendra Arora");
jLabel2.setToolTipText("");
jTable1.setModel(new javax.swing.table.DefaultTableModel(
new Object [][] {
{null, null, null, null},
{null, null, null, null},
},
new String [] {
"Name", "Mobile no.", "City", "Country"
}
) {
Class[] types = new Class [] {
java.lang.String.class, java.lang.Integer.class, java.lang.String.class, java.lang.String.class
};
boolean[] canEdit = new boolean [] {
false, false, false, false
};
public Class getColumnClass(int columnIndex) {
return types [columnIndex];
}
public boolean isCellEditable(int rowIndex, int columnIndex) {
return canEdit [columnIndex];
}
});
jTable1.setToolTipText("");
jScrollPane1.setViewportView(jTable1);
jMenu1.setText("File");
jMenuItem1.setText("New");
jMenuItem1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jMenuItem1ActionPerformed(evt);
}
});
jMenu1.add(jMenuItem1);
jMenuItem2.setText("About");
jMenuItem2.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jMenuItem2ActionPerformed(evt);
}
});
jMenu1.add(jMenuItem2);
jMenuItem3.setText("Exit");
jMenuItem3.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jMenuItem3ActionPerformed(evt);
}
});
jMenu1.add(jMenuItem3);
jMenuBar1.add(jMenu1);
setJMenuBar(jMenuBar1);
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(

答案 0 :(得分：0)
这是你可能想要的
int ans= JOptionPane.showInputDialog(null, "Enter full name", "Enter full name", JOptionPane.INFORMATION_MESSAGE);
if(ans==JOptionPane.OK_OPTION) {
int optionSelected= JOptionPane.showInputDialog(null, "Enter phone number", "Enter phone number", JOptionPane.INFORMATION_MESSAGE);
}
P.S：这只是为了给你一个想法。根据你的需要修改/改进代码。事实上，在发布此答案时，我还没有检查过语法或API。
