从一个“输入对话框”切换到另一个“输入对话框”？

Question

希望你们一切都好..

我正在做一个简单的Phone book diary，所以问题是

当我点击new时，它必须打开一个对话框JOptionPane，

是的，它成功打开了，但是在单击ok 后，我想再次显示一个新对话框来询问电话号码.. 我知道要进行编码，但正在寻找如何做到这一点的逻辑？

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() {

        });

Answer 1

这可能是你想要的

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：这只是给你一个想法。根据需要修改/改进代码。事实上，我在发布此答案时没有检查语法或 API。
