Stupid game, don't play

Beer.java

import java.util.Scanner;
public class Beer{

     public static void main(String []args){
        
        int beer;
        int num;
        
        Scanner scan = new Scanner(System.in);
        
        num = scan.nextInt();
        
        num = 100 - num;
        beer = 100;
        
        while (beer >= num + 1) {
            
            System.out.println ("\n" + beer + " bottles of beer on the wall, " + beer + " bottles of beer");
            
            beer -= 1;
            
            System.out.println ("take one down, pass it around " + beer + " bottles of beer on the wall");
            
        }
        

     }
}

This sucks ass. Now all I do is drink beer. I miss high school.
