Java output lines with each lines containing two string

December 21, 2022

I want to outpot the N lines with each lines containing either Mary or Jobert. I only know how to loop it but I don’t know how it would stop based on the N number

import java.util.Scanner;
class HelloWorld {
    public static void main(String[] args) {
      
      int n= 5;
      
    for (int i = 1; i <= 5; i++) {
      for (int j = 1; j < i; j++) {
      
        System.out.println("Mary ");
       
      }
       for (int k = 1; k < i; k++) {
          System.out.println("Jobert");
       
      }

    }
    }
}

The output is

Mary 
Jobert
Mary 
Mary 
Jobert
Jobert
Mary 
Mary 
Mary 
Jobert
Jobert
Jobert
Mary 
Mary 
Mary 
Mary 
Jobert
Jobert
Jobert
Jobert

but what I want is that it would stop at 5 words since n is 5

Mary 
Jobert
Mary 
Mary 
Jobert

>Solution :

Try below code :

class Test {
    public static void main(String[] args) {
      
        int n = 7;
        int counter = 0;
      
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j < i; j++) {
                if(j > 1) {
                    counter++;
                    System.out.println("Mary ");
                }
                
                if(counter == n) {
                    break;
                }
            }
       
            for (int k = 1; k < i; k++) {
                if(k > 1) {
                    counter++;
                    System.out.println("Mary ");
                }
                
                if(counter == n) {
                    break;
                }
            }
        }
    }
}
