Java return

Question

https://code.sololearn.com/cNcBMv4kD2Sm/?ref=app
this code must create a blank string and do
s = s+"Buzz" to fullfill the lastly return,because the lastly return return a number, got any other easier way instead of this?

Answer 1

public static String ans(int num){

if(num%3 == 0 && num%5 == 0){
return "FizzBuzz";
}else if(num%3 == 0){
return "Fizz";
}else if(num%5 == 0){
return "Buzz";
}else{
return Integer.toString(num);
}
}

I’m kinda too tired to provide an explanation, but this would be an easier way write that. If you have any questions feel free to ask though

Answer 2

//Here's an alternative approach:

public static String ans(int num){

String s = num % 3 == 0 ? "Fizz" : "";
s = num % 5 == 0 ? s + "Buzz" : s;

return s == "" ? Integer.toString(num) : s;

}
