import java.io.*;

import java.util.Scanner;

class Pattern {

public static void main(String args[]) throws IOException {

Scanner sc = new Scanner(System.in);

System.out.println(“::::MENU::::”)

System.out.println(” 1. To display ABCD Pattern”);

System.out.print(” 2. To display Word Pattern”);

System.out.print(“Enter your choice:”);

int ch= sc.nextlnt();

switch(ch) {

case 1: for (char i = ‘E’; i > = ‘A’; i- -){

for(char j = ‘A’;j <=i;j + +){

System.out.print(j);

}

System.out.prindn( );

}

break; case 2:

String S = “BLUE”;

for (int i = 0; i < S.length(); i+ +)

{ for(int j = 0; j < =i; j + +)

{ System.out.print(S.charAt(i));

} System.out.println();

}

break; default:

System.out.println(“Invalid Input”); break;

}
