Java:为什么我的 while 语句不适用于我的案例 2？

Question

我正在尝试创建一个简单的程序，当输入指定的数字时输出歌曲的歌词。问题是我的第二种情况不会输出，而只输出第一种情况。当我尝试输出第二种情况时，它仍然输出第一种情况。不管我是否做了两个 while 语句，这种情况仍然会发生。有人可以帮我修复我的代码吗？

这里是:

import java.util.Scanner;
public class Lyrics {
public static void main (String args[]){
        Scanner input = new Scanner (System.in);
        int one, two, uone, utwo;
        one = 1;
        two = 2;
        System.out.println("Welcome to the Lyrics Finder!");
        System.out.println("Press the number beside the song to see the lyrics!");
        System.out.println("1) Thank For The Memories - Fall Out Boy");
        System.out.println("2) Take Me To Church - Hozier");
        uone = input.nextInt();
        utwo = input.nextInt();
        switch (one){
        case 1:
            //code goes here for option 1
            System.out.println("");
            System.out.println("Thank For The Memories - Fall Out Boy Lyrics");
            System.out.println("         ==          ");
            System.out.println("I'm gonna make it bend and break");
            System.out.println("Say a prayer but let the good times roll");
            System.out.println("In case God doesn't show");
            System.out.println("(Let the good times roll, let the good times roll)");
            System.out.println("And I want these words to make things right");
            System.out.println("But it's the wrongs that make the words come to life");
            System.out.println("Who does he think he is?");
            System.out.println("Who does he think he is?");
            System.out.println("Better put your fingers back to the keys");
            //continue song here
            break;
        case 2:
            //retype all code her for it to reset
            System.out.println("");
            System.out.println("Take Me To Church - Hozier");
            System.out.println("          ==             ");
            System.out.println("My lover's got humour, She's the giggle at a funeral");
            System.out.println("Knows everybody's disapproval, I should've worshipped her sooner");
            System.out.println("If the heavens ever did speak, She's the last true mouthpiece");
            System.out.println("Every Sunday's getting more bleak, A fresh poison each week");
            System.out.println("We were born sick you heard them say it");
            System.out.println("My church offers no absolutes, She tells me Worship in the bedroom");
            break;
  }
        while (uone == one){

            System.out.println("<-=OPTIONS=->");
            System.out.println("Press the number beside the song to see the lyrics!");
            System.out.println("1) Thank For The Memories - Fall Out Boy");
            System.out.println("2) Take Me To Church - Hozier");

            uone = input.nextInt();
            utwo = input.nextInt();
            switch (one){
            case 1:
                //code goes here for option 1
                System.out.println("");
                System.out.println("Thank For The Memories - Fall Out Boy Lyrics");
                System.out.println("         ==          ");
                System.out.println("I'm gonna make it bend and break");
                System.out.println("Say a prayer but let the good times roll");

                System.out.println("");

当用户输入数字一时，应该输出:

System.out.println("");
                System.out.println("Thank For The Memories - Fall Out Boy Lyrics");
                System.out.println("         ==          ");
                System.out.println("I'm gonna make it bend and break");
                System.out.println("Say a prayer but let the good times roll");
                System.out.println("In case God doesn't show");
                System.out.println("(Let the good times roll, let the good times roll)");
                System.out.println("And I want these words to make things right");
                System.out.println("But it's the wrongs that make the words come to life");
                System.out.println("Who does he think he is?");
                System.out.println("Who does he think he is?");
                System.out.println("Better put your fingers back to the keys");
                //continue song here
                break;
while (uone == one){
                System.out.println("");
                System.out.println("<-=LYRICS ABOVE=->");
                System.out.println("<-=OPTIONS=->");
                System.out.println("Press the number beside the song to see the lyrics!");
                System.out.println("1) Thank For The Memories - Fall Out Boy");
                System.out.println("2) Take Me To Church - Hozier");

当用户输入数字 2 时，应该输出:

System.out.println("");
                System.out.println("Take Me To Church - Hozier");
                System.out.println("          ==             ");
                System.out.println("My lover's got humour, She's the giggle at a funeral");
                System.out.println("Knows everybody's disapproval, I should've worshipped her sooner");
                System.out.println("If the heavens ever did speak, She's the last true mouthpiece");
                System.out.println("Every Sunday's getting more bleak, A fresh poison each week");
                System.out.println("We were born sick you heard them say it");
                System.out.println("My church offers no absolutes, She tells me Worship in the bedroom");
                break;
while (uone == one){
                System.out.println("");
                System.out.println("<-=LYRICS ABOVE=->");
                System.out.println("<-=OPTIONS=->");
                System.out.println("Press the number beside the song to see the lyrics!");
                System.out.println("1) Thank For The Memories - Fall Out Boy");
                System.out.println("2) Take Me To Church - Hozier");

请注意，我对编码非常陌生，因此请尽力解释。如果没有，我仍然可以理解，但无论如何，请简要解释一下您的解决方案。

Answer 1

改变

    uone = input.nextInt();
    utwo = input.nextInt();
    switch (one){

至

    int choice = input.nextInt();

    switch (choice)
