我希望输入不区分大小写

Question

例如,当用户键入"九月","九月","九月","九月"或无论如何,只要字母正确,它就是一个有效的条目.什么是编写此代码的更简洁的方法(我使用"||"的部分.)？

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Compare {

    public static void main(String[] args) {
        String s1 = getInput("Enter a month ");
        if(s1.equals("February")) {
            System.out.println("It's time to go to the Disneyland !");
            String s2 = getInput("Enter another month: ");
            if(s2.equals("February")) {
                System.out.println("You already won a Disneyland ticket! Try       another month.");
                String s3 = getInput("Enter another month: ");
                  if(s3.equals("January") || 
                     s3.equals("March") || 
                     s3.equals("April") || 
                     s3.equals("July") || 
                     s3.equals("May") || 
                     s3.equals("September") || 
                     s3.equals("October") || 
                     s3.equals("November") || 
                     s3.equals("Aguest") || 
                     s3.equals("July") || 
                     s3.equals("December")) {
                     System.out.println("You will go to Paris");
                  }else {
                     String s4 = getInput("Leave your name and phone number. We will call you back. ");
                     System.out.println("Thanks for visiting! Goodbye !");
                   }    
              }
         }
     }
    private static String getInput(String prompt) {
        BufferedReader stdin = new BufferedReader(
                new InputStreamReader(System.in));
        System.out.print(prompt);
        System.out.flush();

        try {
            return stdin.readLine();
        } catch (Exception e) {
            return "Error: " + e.getMessage();
          }

     }

}

使用时String.equalsIgnoreCase(),它会不敏感地检查字符串是否相等.[ 文件 ]
