Java Program to Print X inside Rectangle Star Pattern

In this Java pattern program, we show the steps to print the X pattern inside a rectangle star shape 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 pattern inside the rectangle shape of the stars.

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 Rows = ");
		int rows = sc.nextInt();
		
		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("*");
				}
			}
			System.out.println();
		}
	}
}

Enter Rows = 14

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 stars pattern. For more star pattern programs, please click here.

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 Rows = ");
		rows = sc.nextInt();
		
		System.out.print("Enter Character = ");
		char a = sc.next().charAt(0);
		
		i = 0 ; 
		while (i < rows ) 
		{
			j = 0 ; 
			while (j < rows ) 	
			{
				if (i == j || i + j == rows - 1) 
				{
					if (i + j == rows - 1) 
					{
						System.out.printf("/");
					} 
					else 
					{
						System.out.printf("\\");
					}
				} 
				else 
				{
					System.out.printf("%c", a);
				}
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

In this Java pattern program, we created the XinRectangleStars function to print the X shape inside rectangle stars 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 Rows = ");
		int rows = sc.nextInt();
		
		XinRectangleStars(rows);
	}
	
	public static void XinRectangleStars(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("*");
				}
			}
			System.out.println();
		}
	}
}
