How many times will the following loop execute?

int a = 5;
while (a > 0) {
    System.out.println(a-- + 2);
    if (a % 2 == 0)
        break;
}

How many times will the following loop execute? Write the output of the code:

int x=10; 
while (true){
System.out.println(x++ * 2);
if(x%3==0)
break;
} 

Define a class to accept a four digit number and check whether it is a Framul Number or not. A number is called a Framul Number if the product of all its digits equals fives times the sum of its first and last digit.

Example 1:

Input: 1325
Product of all digits = 1 x 3 x 2 x 5 = 30
Five times sum of first & last digit = 5 x (5 + 1) = 5 x 6 = 30

Output: Framul Number

Example 2:

Input: 2981
Product of all digits = 2 x 9 x 8 x 1 = 144
Five times sum of first & last digit = 5 x (1 + 2) = 5 x 3 = 15

Output: Not a Framul Number

If the entered number is not of four digits, the message "Please enter a four digit number" should be shown.

import java.util.Scanner;

public class KboatFramulNumber
{
    public static void main(String args[]) {
        Scanner sc = _____(1)_____
        
        System.out.print("Enter a four-digit number: ");
        int num = _____(2)_____
        
        _______(3)_______ {
            System.out.println("Please enter a four-digit number");
            return;
        }
        
        int d = 0;
        int f = num % 10;
        int p = 1;
        
        _______(4)_______ {
            _____(5)_____
            _____(6)_____
            _____(7)_____
        }

        int s =  _____(8)_____

        if (p == s) {
            _______(9)_______
        } else {
            _______(10)_______
        }
        
    }
}
