Java Program to Print X inside Rectangle Numbers Pattern

In this Java pattern program, we show the steps to print the X shape inside a rectangle numbers pattern using for loop, while loop, and functions. The below program accepts the user-entered rows and uses the nested for loop and if else to traverse the rows and columns. Next, the program will print the X shape inside a rectangle pattern of numbers.

import java.util.Scanner;

public class Example 
{
	private static Scanner sc;
	
	public static void main(String[] args) 
	{
		sc = new Scanner(System.in);
		int rows, i, j;
		
		System.out.print("Enter Numbers of Rows = ");
		rows = sc.nextInt();
		
		for (i = 0 ; i < rows; i++ ) 
		{
			for (j = 0 ; j < rows; j++ ) 	
			{
				if (i == j || i + j == rows - 1)
				{
					if (i + j == rows - 1)
					{
						System.out.printf("/");
					}
					else
					{
						System.out.printf("\\");
					}
				}
				else
				{
					System.out.printf("%d", i);
				}
			}
			System.out.println();
		}
	}
}

Enter Numbers of Rows = 10
\00000000/
1\111111/1
22\2222/22
333\33/333
4444\/4444
5555/\5555
666/66\666
77/7777\77
8/888888\8
/99999999\

Within this program, we replaced the for loop with a while loop to traverse the rows and columns and print the X shape inside the rectangle numbers pattern. For more Number pattern programs, please click here.

		{

			{

				{

					}

					}
				}

				{
					System.out.printf("%d", i);

			}

In this Java pattern program, we created the XinRectangleNumbers function to print the X shape inside the rectangle numbers pattern.

import java.util.Scanner;

public class Example 
{
	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();
		
		XinRectangleNumbers(rows);
			
	}
	public static void XinRectangleNumbers(int rows) 
	{
		for (int i = 0 ; i < rows; i++ ) 
		{
			for (int j = 0 ; j < rows; j++ ) 	
			{
				if (i == j || i + j == rows - 1)
				{
					if (i + j == rows - 1)
					{
						System.out.printf("/");
					}
					else
					{
						System.out.printf("\\");
					}
				}
				else
				{
					System.out.printf("%d", i);
				}
			}
			System.out.println();
		}
	}
}
