Java赋值、输入选择

Question

我的代码需要帮助:我是 Java 新手

输入选项后，如何获取字符串“user”变量来显示我的选择？

import javax.swing.JOptionPane;                 
import java.util.Scanner;
public class Assignment {
    public static void main(String[] args) {
        // TODO code application logic here
        Scanner input = new Scanner( System.in );
        String me = JOptionPane.showInputDialog("Please input name!");
        System.out.println("Your name is: " + me);
        String user = JOptionPane.showInputDialog("Please enter your choice!");
        System.out.println("Your choice is: " + user);
        JOptionPane.showMessageDialog(null, "Your choice is: " + user);

            if(user.equals('1'))

            JOptionPane.showMessageDialog(null, "Username" + me + user);
    }  
}

Answer 1

比较字符串时使用双引号

 if(user.equals("1"))  // double quotes

            JOptionPane.showMessageDialog(null, "Username" + me + user);
