Question

Java Write a menu driven program to input the total number of rows and print the following patterns depending upon the user’s choice. If choice is 1 then print the number pattern , if choice is 2, print the character pattern , else print error message “invalid choice”. Use switch-case statement to check choice and to print accordingly. For example : Total number of rows = 5 Choice = 1 Choice = 2 5 A B C D E 4 5 A B C D 3 4 5 A B C 2 3 4 5 A B 1 2 3 4 5 A

ANSWER

import java.util.Scanner;

public class KboatPattern

{

public void choosePattern() {

Scanner in = new Scanner(System.in);

System.out.println("Type 1 for Floyd's triangle");

System.out.println("Type 2 for an ICSE pattern");

System.out.print("Enter your choice: ");

int ch = in.nextInt();

switch (ch) {

case 1:

int a = 1;

for (int i = 1; i <= 5; i++) {

for (int j = 1; j <= i; j++) {

System.out.print(a++ + "\t");

}

System.out.println();

}

break;

case 2:

String s = "ICSE";

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

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

System.out.print(s.charAt(j) + " ");

}

System.out.println();

}

break;

default:

System.out.println("Incorrect Choice");

}

}

}
