Question

JAVA

If a user inputs a specific number of rows, columns and sections for a rectangle using three symbols, how would you print using for loops and a string? Not using an array

Example:

If 4 was inputted for rows, 12 was inputted for columns, 6 was inputted for sections, and the following symbols (that are all chosen by the user) were “$” “*” and “%” the following would print:

$$**%%$$**%%

$$**%%$$**%%

$$**%%$$**%%

$$**%%$$**%%

Has to account for all numbers including odd. And the three symbols repeat.

Below is the code for the above code:

import java.util.Scanner;

public class Rectangle {

   /**main method to start the program*/
   public static void main(String[] args) {
      
      
       int rows;
       int columns;
       int section;
       char symbol1;
       char symbol2;
       char symbol3;
      
       /**taking input from the users*/
       Scanner input = new Scanner(System.in);
       System.out.println("Enter the number of rows");
       rows = input.nextInt();
       System.out.println("Enter the number of columns");
       columns = input.nextInt();
       System.out.println("Enter the sections");
       section = input.nextInt();
       System.out.println("Enter the symbol 1");
       symbol1 = input.next().charAt(0);
       System.out.println("Enter the symbol 2");
       symbol2 = input.next().charAt(0);
       System.out.println("Enter the symbol 3");
       symbol3 = input.next().charAt(0);
      
       int innerlooptimes = (int) Math.ceil(section/3);

       /**outer loop will run for row times*/
       for(int i = 0;i<rows; i++ )
       {
           /**2nd inner class will run for column/section times*/
           for(int j=0; j<(int)Math.ceil(columns/section); j++)
           {
               /**there are 3 symbols, so 3rd inner loop will run for 3 times*/
               for(int k=0;k<3;k++)
               {
                  
                   if(k%3==0)
                   {
                       /**most inner loop will run for section/3 times*/
                       for(int p =0; p<innerlooptimes;p++)
                       System.out.print(symbol1);
                   }
                   else if(k%3==1)
                   {
                       for(int p =0; p<innerlooptimes;p++)
                       System.out.print(symbol2);
                   }
                   else
                   {
                       for(int p =0; p<innerlooptimes;p++)
                       System.out.print(symbol3);
                   }
               }
           }
           System.out.println();
       }
      
       /**if you calculate number of time inner loops will run , (Column/section)*(3)*(section/3) = columns
       * */
   }

}

output:
