Java - Recursion with String returning with 0 -

i want homecoming string "electric" number user inputs. have created program. problem it's returning 0 rather showing output only. know problem is, don't know right solution.

example :

input : 3

output :

electric electric electric 0 <- should not have 0 here.

import java.io.*; public class quitx{ public static bufferedreader v = new bufferedreader(new inputstreamreader(system.in)); public static int s; public static void main(string[] args) throws exception{ system.out.println("enter integer : "); s = integer.parseint(v.readline()); system.out.println(x(s)); } public static int x(int s){ if(s <= 0) homecoming s; else{ system.out.println("electric!"); homecoming x (s - 1); } } }

the x() method returns int. don't want int printed. yet you're calling

system.out.println(x(s));

if don't want result printed, then... don't print it:

x(s);
