Answer by user2023861 for FizzBuzz Problem Solution

You have four calls to System.out.println(arg). If you want to change your code from printing to the console to writing to a file or a database, you have to change four lines in your code even though you're really only changing one "thing". Why not pull out the four System.out.println(arg)s and insert one after the if conditions like so:

public class FizzBuzz{  public static void main(String[] args){    for(int i = 1 ; i <= 100 ; ++i){      String str;      if(i % (5*3) == 0){        str = "FizzBuzz";      }else if(i % 3 == 0){        str = "Fizz";      }else if(i % 5 == 0){        str = "Buzz";      }else        str = Integer.toString(i);       System.out.println(str);    }  }}

I agree with others that your if conditions are ugly.
