Java Program to Print X Pattern of Alphabets

In this Java pattern program, we show the steps to print the X pattern of alphabets using for loop, while loop, and functions. The below program accepts the user-entered rows and uses the nested for loop to traverse the rows and columns. Next, the If else statement helps to print the alphabet in an X 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();
		
		int a = 65;

		for (int i = 0 ; i < rows; i++ ) 
		{
			for (int j = 0 ; j < rows; j++ ) 	
			{
				if (i == j || j == rows - 1 - i)
				{
					System.out.printf("%c", a  + j);
				}
				else
				{
					System.out.printf(" ");
				}			
			}
			System.out.println();
		}
	}
}

Enter Numbers of Rows = 11
A         K
 B       J 
  C     I  
   D   H   
    E G    
     F     
    E G    
   D   H   
  C     I  
 B       J 
A         K

Within this program, we replaced the for loop with a while loop to traverse the rows and columns of X and print the alphabet in an X pattern shape. For more Alphabet Patterns, 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, a = 65;
		
		System.out.print("Enter Numbers of Rows = ");
		rows = sc.nextInt();

		i = 0 ;
		while (i < rows ) 
		{
			j = 0 ;
			while (j  < rows ) 	
			{
				if (i == j || j == rows - 1 - i)
				{
					System.out.printf("%c", a  + j);
				}
				else
				{
					System.out.printf(" ");
				}	
				j++;
			}
			System.out.println();
			i++;
		}
	}
}

Enter Numbers of Rows = 15
A             O
 B           N 
  C         M  
   D       L   
    E     K    
     F   J     
      G I      
       H       
      G I      
     F   J     
    E     K    
   D       L   
  C         M  
 B           N 
A             O

In this Java pattern program, we created an XPatternofAlpha function to print the X shape or pattern of user-given rows filled with the alphabet.

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();
		
		XPatternofAlpha(rows);
	}
	
	public static void XPatternofAlpha(int rows)
	{
		int a = 65;

		for (int i = 0 ; i < rows; i++ ) 
		{
			for (int j = 0 ; j < rows; j++ ) 	
			{
				if (i == j || j == rows - 1 - i)
				{
					System.out.printf("%c", a  + j);
				}
				else
				{
					System.out.printf(" ");
				}			
			}
			System.out.println();
		}
	}
