Java Program to Print Same Numbers in Rectangle Rows and Columns

Write a Java program to print same numbers in rectangle rows and columns pattern using for loop.

import java.util.Scanner;

public class sameNuminRowsCols1 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Numbers of Rows = ");
		int rows = sc.nextInt();
		
		System.out.print("Enter Numbers of Columns = ");
		int columns = sc.nextInt();
		
		System.out.println("Printing Same Numbers in Rows and Columns");
		
		for (int i = 1 ; i <= rows; i++ ) 
		{
			for (int j = i ; j < i + columns; j++ ) 	
			{
				System.out.printf("%d", j);
			}
			System.out.println();
		}
	}
}

This Java example displays the rectangle pattern where rows and columns have the same numbers using a while loop.

import java.util.Scanner;

public class sameNuminRowsCols2 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		int i = 1, j;
		
		System.out.print("Enter Numbers of Rows and Columns = ");
		int rows = sc.nextInt();
		int columns = sc.nextInt();
		
		System.out.println("Printing Same Numbers in Rows and Columns");
		
		while(i <= rows ) 
		{
			j = i ;
			
			while ( j < i + columns ) 	
			{
				System.out.printf("%d", j);
				j++;
			}
			
			System.out.println();
			i++;
		}
	}
}

Java program to print the same numbers in rectangle rows and columns using do while loop.

import java.util.Scanner;

public class sameNuminRowsCols3 {
	
	private static Scanner sc;
	
	public static void main(String[] args) {
		
		sc = new Scanner(System.in);	
		
		System.out.print("Enter Numbers of Rows and Columns = ");
		int rows = sc.nextInt();
		int columns = sc.nextInt();
		
		System.out.println("Printing Same Numbers in Rows and Columns");
		int i = 1, j;
		
		do
		{
			j = i ;
			
			do 	
			{
				System.out.printf("%d", j);

			} while ( ++j < i + columns );
			
			System.out.println();

		} while(++i <= rows );
	}
}
