In this post, we will learn “How to repeat a string N number of times in Java 11?”. Java 11 introduced a new method called repeat(N) to do that.
Here, we are going to learn following things:

Let’s Begin,
1. What is repeat(N) method?
repeat(N) is a string method of String class.
This method returns a string whose value is the concatenation of this string repeated count times. If this string is empty or count is zero then the empty string is returned.
Syntax:
1 2 3 4 5 6 7 8 9 10 11 12 13 | /** * @param count number of times to repeat * * @return A string composed of this string repeated * {@code count} times or the empty string if this * string is empty or count is zero * * @throws IllegalArgumentException if the {@code count} is * negative. * * @since 11 */ public String repeat(int count) |
2. How to use it?
Let’s take an example where we are repeating a word ‘Techndeck’ 5 times.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | public class Repeat_String_Java11 { public static void main(String[] args) { var S = "Techndeck"; //Repeat the above string 5 times using Java 11 var newS = S.repeat(5); System.out.println("Value of the newS is: " + newS); } } |
Output:
1 | Value of the newS is: TechndeckTechndeckTechndeckTechndeckTechndeck |
