Pattern 8

We can print the following Pattern 
1) 
    1             //print (char)(j+64) and i
   A B 
  3 3 3 
 A B C D 

2)
    1            //print (char)(j+64) and j
   A B 
  1 2 3 
 A B C D 

3)
    1            //print (char)(i+64) and i
   B B 
  3 3 3 
 D D D D 

4)
    1          //print (char)(i+64) and j
   B B 
  1 2 3 
 D D D D 




package demo;

import java.util.Scanner;

public class Pattern9 {
 public static void main(String[] args) {
  Scanner sc = new Scanner(System.in);
  
  System.out.println("Enter the number");
  int n=sc.nextInt();

  for(int i=1;i=i;k--) {
    System.out.print(" ");
   }
   for(int j=1;j<=i;j++) {
    //System.out.print("* ");
    if(i%2 == 0) {
     System.out.print((char)(i+64)+ " ");
    }
    else
    {
     System.out.print(j+ " ");
    }
   }
   System.out.println();
  }
 }
}
