Printing a string multiple times

Question

I'm trying to figure out how to print any inputted string multiple times in java. This is what I have thus far...

public class Main{

    public static String printGivenStringTimesNumberGiven(String str, int n) {
        for (int i=0; i<n; i++)
            str += n;
        return str;
    }

    //Don't touch here
    public static void main(String[] args){
        System.out.println(printGivenStringTimesNumberGiven("Ha", 3));
    }
}

I keep on getting Ha333 multiple times and I'm not sure where to go from here. Any help would be appreciated. I'm trying to get it to print out HaHaHa.

Welcome to Java world :) Basically, you created a method which has parameters as a String and the given number, in this case, it is 3. You can start looking at how to debug at http://www.vogella.com/tutorials/EclipseDebugging/article.html to understand more about what you have done so far. — Tuan Hoang, Nov 25 '17 at 04:26

This should work in your case:

public class Main{
public static String printGivenStringTimesNumberGiven(String str, int n) {
   String s = str;
   for(int i = 0; i< n-1;i++)
       s = s +" " + " " + str;
return s;
}

//Don't touch here
public static void main(String[] args){
    System.out.println(printGivenStringTimesNumberGiven("Ha", 3));
}
}

I have to use some kind of return statement in the method. – boldercoder Nov 25 '17 at 04:50
@boldercoder in imperative languages you can't call a function one time and return something n times. – Luai Ghunim Nov 25 '17 at 05:03
I don't think we're allowed to change the method from a String to a void in the problem though. – boldercoder Nov 25 '17 at 05:10
I edited the answer but it's no good style :) – Luai Ghunim Nov 25 '17 at 05:14
