Print a string N number of times in Java

In this tutorial, we will see – How to Print a string N number of times in Java using various methods.

A string is a sequence of characters. The String class in Java is used to create and implement string objects. It basically has the implementation of a character array.

Printing a string N times

We can do this in various ways. Some of them are:

1. Using for loop
2. Taking input for N
3. Using the repeat() method

Print a string N number of times, once in each line in Java

my_string: CodeSpeedy
N: 5
Output: CodeSpeedy
        CodeSpeedy
        CodeSpeedy
        CodeSpeedy
        CodeSpeedy

Java Code for this is as follows

public class Main
{
  public static void main(String[] args) {
    String my_string = "CodeSpeedy";
    int N = 5;
    
    //print once in each line
    for (int i =0; i<5; i++){
        System.out.println(my_string);
    }
   }
}

Print a string N number of times in a single line in Java

my_string: CodeSpeedy
N: 4
Output: CodeSpeedyCodeSpeedyCodeSpeedyCodeSpeedy

Java Code for this is as follows

public class Main
{
  public static void main(String[] args) {
    String my_string = "CodeSpeedy";
    int N = 5;
    
    //print N times in one line
    for (int i =0; i<5; i++){
        System.out.print(my_string);
    }
   }
}

Taking input for N

We can take input in Java using the Java Scanner class of java.util.Scanner.

Input:
        my_string: Java is Fun!
        N: 3
Output: Printing the string N times in a single line.
        Java is Fun!Java is Fun!Java is Fun!

        Printing the string N times, once in each line
        Java is Fun!
        Java is Fun!
        Java is Fun!

Java Code for this is as follows

import java.util.Scanner;

public class Main
{
  public static void main(String[] args) {
      
      Scanner a = new Scanner(System.in);
      System.out.print("my_string: ");
        String my_string = a.nextLine();
      System.out.print("N: ");
        int N = a.nextInt();
    
    System.out.println("Printing the string" + N + "times in a single line.");
    for (int i =0; i<5; i++){
        System.out.print(my_string);
    }
    
    System.out.println("\n\nPrinting the string" + N + "times, once in each line");
    for (int i =0; i<5; i++){
        System.out.println(my_string);
    }
    }
}

Using the repeat() method

Java11 has a method to do this very easily. We can use the repeat() method of org.apache.commons.lang3 package for this. The method can be used as my_string.repeat(n)

Input:
        my_string: Java 11.
        N: 4
Output: Java 11.Java 11.Java 11.Java 11.

Java Code for this is as follows

import org.apache.commons.lang3.StringUtils;
import java.util.Scanner;


public class Main
{
  public static void main(String[] args) {
      
      Scanner a = new Scanner(System.in);
      System.out.print("my_string: ");
        String my_string = a.nextLine();
      System.out.print("N: ");
        int N = a.nextInt();
       
        String repeated = my_string.repeat(3);
        System.out.print(repeated);
  
    }
}
