Trying to learn JAVA and I want to write 99 bottles of beer song

Question

I am very new to JAVA programming and have only programmed in Python before. I'm trying to figure out why I'm getting a duplicate line of " # of bottles of beer on the wall" when I execute my code.

    package BeerBottle;

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

      while (beerNum > 0) {

      if (beerNum == 1) {
      word = "bottle";
      } else {
      word = "bottles";
      }
    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"); // I think it might be this line but I need it 
    } else {
        System.out.println("No more bottles of beer on the wall");
    }
    }
   }

}

The result I get is this:

    2 bottles of beer on the wall
    2 bottles of beer on the wall (duplicate)
    2 bottles of beer
    Take one down
    pass it around
    1 bottles of beer on the wall
    1 bottle of beer on the wall (duplicate)
    1 bottle of beer
    Take one down
    pass it around
    No more bottles of beer on the wall

Thank you for your help

Answer 1

The last printed line of the loop is identical to the first printed line of the next loop, so it's not a problem. To visually separate each loop's output, print a blank line at the very end of the method. Then you'll see something like this:

2 bottles of beer on the wall  // Last line of a loop

2 bottles of beer on the wall  // First line of the next loop
2 bottles of beer
Take one down
pass it around
1 bottles of beer on the wall  // Last line of a loop

1 bottle of beer on the wall   // First line of next loop
1 bottle of beer
Take one down
pass it around
No more bottles of beer on the wall
