试着编码99瓶啤酒歌

Question

public class apples {
    public static void main(String[] args) {
        int beerNum = 99;
        String word = "bottles";

        while (beerNum > 0) {

            if (beerNum == 1) {
                word = "bottle"; // ONE bottle
            }

            System.out.println(beerNum + " " + word + " of beer on the wall, " + beerNum + " " + word + " of beer");
            beerNum = beerNum - 1;

            if (beerNum > 0) {
                System.out.println("Take one down, pass it round " + beerNum + " " + word + " of beer");
            }
        }

        if (beerNum == 0) {
            System.out.println("No more bottles of beer");
        }

    }
}

99 bottles of beer on the wall, 99 bottles of beer
Take one down, pass it round 98 bottles of beer
98 bottles of beer on the wall, 98 bottles of beer
Take one down, pass it round 97 bottles of beer
97 bottles of beer on the wall, 97 bottles of beer
Take one down, pass it round 96 bottles of beer
96 bottles of beer on the wall, 96 bottles of beer
Take one down, pass it round 95 bottles of beer
95 bottles of beer on the wall, 95 bottles of beer... 

(And so on and so forth)

3 bottles of beer on the wall, 3 bottles of beer
Take one down, pass it round 2 bottles of beer
2 bottles of beer on the wall, 2 bottles of beer
Take one down, pass it round 1 bottles of beer
1 bottle of beer on the wall, 1 bottle of beer
No more bottles of beer

在“墙上一瓶啤酒，一瓶啤酒”之后，也没有说“拿一瓶下来，传一圈”

尝试以下代码：

public class BeerSong{
public static void main (String[] args){
    int beerNum = 99;
    String word = "bottles";
    while(beerNum > 0){
        if (beerNum == 1){
            word = "bottle";
        }
        System.out.println(beerNum + " " + word + " of beer on the wall");
        System.out.println(beerNum + " " + word + " of beer.");
        System.out.println("Take one down.");
        System.out.println("Pass it around.");
        beerNum = beerNum - 1;

        if (beerNum > 0){
            System.out.println(beerNum + " " + word + " of beer on the wall");
            System.out.println("***************************");
        }else {
            System.out.println("No more bottles of beer on the wall");
        }
    }
}
}

它将运行与墙上的1瓶啤酒输出。要100%更正此代码
，只需移动if语句

beerNum = beerNum - 1;
        if (beerNum == 1){
            word = "bottle";
        }

之后

beerNum = beerNum - 1;

public class BeerSong{
public static void main (String[] args){
    int beerNum = 99;
    String word = "bottles";
    while(beerNum > 0){
        System.out.println(beerNum + " " + word + " of beer on the wall");
        System.out.println(beerNum + " " + word + " of beer.");
        System.out.println("Take one down.");
        System.out.println("Pass it around.");

        beerNum = beerNum - 1;
        if (beerNum == 1){
            word = "bottle";
        }
        if (beerNum > 0){
            System.out.println(beerNum + " " + word + " of beer on the wall");
            System.out.println("***************************");
        }else {
            System.out.println("No more bottles of beer on the wall");
        }
    }
}
}
