Program to Print Digit 8 Character Pattern

In the previous article, we have discussed Java Program to Print Plus Character Pattern

In this article we are going to see how to print the number ‘8’ character pattern.

Example:

Size :  8

AAAA 
B      B
C      C
D      D
E       E
  FFFF 
G     G
H     H
I        I
J       J

Now, let’s see the actual program to print it.

Don’t stop learning now. Get hold of all the important Java fundamentals with the Simple java program example guide and practice well.

Approach:

  • Enter the size and store it in an integer variable size.
  • Take first for loop to print all rows.
  • Take second/inner for loop to print column values.
  • Then go on printing the star symbols according to the iteration and if else condition.

Java Code to Print Digit 8 Character Pattern

import java.util.Scanner;
class Main
{
    public static void main(String[] args)  
    {  
        //starting ascii value taken 64
        int ascii=64;
        Scanner scan = new Scanner(System.in);
        System.out.print("Size : ");
        //Taking size as input from user
        int r, c, size=scan.nextInt();
        int k = size*2-1;
        for(r = 1; r<=k; r++)
        {
            //Outer loop
            if(r==1||r==size||r==k)
                for(c = 1;c<=size;c++)
                {
                    //Inner Loop 1
                    if(c==1||c==size)
                        System.out.print(" ");
                    else
                        System.out.print((char)(r+ascii));
                }
            else
                for(c = 1;c<=size;c++)
                {
                    //Inner loop 2
                    if(c==1||c==size)
                        System.out.print((char)(r+ascii));
                    else
                        System.out.print(" ");
                }
                    //Prints a new line
            System.out.println();
        }
    }
}
Output:

Size : 8
 
AAAA 
B     B
C     C
D    D
E     E
 FFFF 
G    G
H    H
I       I
J       J
