如何仅使用“ switch and if”在Java解决方案中创建这样的输入“ January”，“ january”，“ JANUARY”，“ janUARY”以及任何其他大小写组合，都将被视为“ January”，并且在所有情况下均输出1。做过程序，但是它只能使用相同的输入词，也许可以解决这个问题。

import java.util.Scanner;
    public class nameMonth
    {

       public static void main(String[] args)

       {
          String month;
          int nrMonth;

      Scanner keyboard = new Scanner(System.in);
      System.out.println("Enter a month");
      month = keyboard.nextLine();
      switch (month)
      {
         case "January":
            System.out.println("Your month is January");
            nrMonth = 1;
            break;

         case "February":
            System.out.println("Your month is February");
            nrMonth = 2;
            break;

         case "March":
            System.out.println("Your month is March");
            nrMonth = 3;
            break;

         case "April":
            System.out.println("Your month is April");
            nrMonth = 4;
            break;

         case "May":
            System.out.println("Your month is May");
            nrMonth = 5;
            break;

         case "June":
            System.out.println("Your month is June");
            nrMonth = 6;
            break;

         case "July":
            System.out.println("Your month is July");
            nrMonth = 7;
            break;

         case "August":
            System.out.println("Your month is August");
            nrMonth = 8;
            break;

         case "September":
            System.out.println("Your month is September");
            nrMonth = 9;
            break;

         case "October":
            System.out.println("Your month is October");
            nrMonth = 10;
            break;

         case "November":
            System.out.println("Your month is November");
            nrMonth = 11;
            break;

         case "December":
            System.out.println("Your month is December");
            nrMonth = 12;
            break;

         default:
            System.err.println("Your month is wrong");
            break;
      }
   }

}

最佳答案

用这个：

switch (month.toUpperCase()) {

然后，大小写应为大写，例如：

    case "JANUARY":
        System.out.println("Your month is January");
        nrMonth = 1;
        break;
