如何在 Java GUI 中进行多项选择

如何解决如何在 Java GUI 中进行多项选择

这个程序应该是为想要预订宴会厅并要求用户回答有关活动的一些简单问题的人准备的。对于膳食计划、房间类型和 10 天问题，我只想有两个选项供用户选择，并且用户单击其中一个选项。所以就像一个多项选择。我尝试查找内容，但我找到的所有教程都是针对多项选择测验的控制台版本。我知道一种方法是使用 JButtons，但我想知道是否有更用户友好的方法来做到这一点。

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JLabel;
import javax.swing.JButton;
import javax.swing.JTextField;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
abstract class Main implements ActionListener{
  public static void main(String[] args) {
    
        JFrame frame = new JFrame("Catering Company");
        frame.setSize(770,490);
        frame.setVisible(true);

        JPanel panel = new JPanel();
        panel.setLayout(null);

        JLabel DayLabel = new JLabel("What day of the week is it?:");
        DayLabel.setBounds(150,80,200,20);
        JTextField DayLabelTXT = new JTextField(5);
        DayLabelTXT.setBounds(360,70,25);

        JLabel AdultCount = new JLabel("How many adults are there?:");
        AdultCount.setBounds(145,120,220,20);
        JTextField AdultCountTXT = new JTextField(5);
        AdultCountTXT.setBounds(360,25);

        JLabel ChildCount = new JLabel("How many children are there?:");
        ChildCount.setBounds(134,160,225,20);
        JTextField ChildCountTXT = new JTextField(5);
        ChildCountTXT.setBounds(360,25);

        JLabel MealPlan = new JLabel("Choose a meal plan:");
        MealPlan.setBounds(208,20);


        JLabel room = new JLabel("Which room would you like to choose?:");
        room.setBounds(78,240,280,20);

        JLabel TenDays = new JLabel("Will you pay within the next 10 days?:");
        TenDays.setBounds(85,275,20);

        JLabel initialDep = new JLabel("What is your initial deposit:");
        initialDep.setBounds(155,320,20);
        JTextField initialDepTXT = new JTextField(5);
        initialDepTXT.setBounds(360,25);



        panel.add(DayLabel);
        panel.add(DayLabelTXT);

        panel.add(AdultCount);
        panel.add(AdultCountTXT);

        panel.add(ChildCount);
        panel.add(ChildCountTXT);

        panel.add(MealPlan);

        panel.add(room);

        panel.add(TenDays);

        panel.add(initialDep);
        panel.add(initialDepTXT);

        frame.add(panel);
  }
}

解决方法

我认为您有多种选择可以做到这一点，您可以使用 JRadioButton、JComboBox 或 JCheckBox，因为您有多种选择，我认为 JCheckBox 是最好的选择你，看看来自https://docs.oracle.com/ :

的这个例子

//In initialization code:
chinButton = new JCheckBox("Chin");
chinButton.setMnemonic(KeyEvent.VK_C); 
chinButton.setSelected(true);

glassesButton = new JCheckBox("Glasses");
glassesButton.setMnemonic(KeyEvent.VK_G); 
glassesButton.setSelected(true);

hairButton = new JCheckBox("Hair");
hairButton.setMnemonic(KeyEvent.VK_H); 
hairButton.setSelected(true);

teethButton = new JCheckBox("Teeth");
teethButton.setMnemonic(KeyEvent.VK_T); 
teethButton.setSelected(true);

结果：
