如何在 Java 中创建输入弹出窗口（对话框），并从用户处获取输入？

使用 JOptionPane.showInputDialog() 从对话框获取用户输入，例如 “哪项运动你最擅长”， “你的名字是啥”，等等。以下是创建输入弹出窗口（对话框）并从用户处获取输入的示例 −

示例

package my;
import javax.swing.JOptionPane;
public class SwingDemo {
   public static void main(String[] args) {
      String[] sports = { "Football", "Cricket", "Squash", "Baseball", "Fencing", "Volleyball", "Basketball" };
      String res = (String) JOptionPane.showInputDialog(null, "Which sports you play the most?", "Sports",
         JOptionPane.PLAIN_MESSAGE, null, sports, sports[0]);
      switch (res) {
         case "Football" −
            System.out.println("I Love Football");
         break;
         case "Cricket" −
            System.out.println("I Love Cricket");
         break;
         case "Squash" −
            System.out.println("I Love Squash");
         break;
         case "Baseball" −
            System.out.println("I Love Baseball");
         break;
         case "Fencing" −
            System.out.println("I Love Fencing");
         break;
         case "Volleyball" −
            System.out.println("I Love Volleyball");
         break;
         case "Basketball" −
            System.out.println("I Love Basketball");
         break;
      }
   }
