如何在Java中创建解决方案只与“开关和如果”这样的输入“一月”或“一月”[重复]

Question

如何在Java中创建解决方案，只要用“switch和if”这样一个输入“january”、“january”、“january”、“january”和任何其他大小写的组合都被视为“january”，并且在所有情况下都打印出1。我做了程序，但它只是与相同的输入词工作，也许存在一个技巧来解决这个问题。

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;
      }
   }

}

Answer 1

你能做到的。

      String month;
      int nrMonth;
      month.toUpperCase(); // Convert to Upper Case.

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