Slip No 27 Q A

Q.Write a java program to accept a number from user, If it is greater than 1000 then throw user defined exception “Number is out of Range” otherwise display the factors of that number. (Use static keyword) [15 M]

import java.util.Scanner;

// User defined exception
class NumberOutOfRangeException extends Exception
{
    public NumberOutOfRangeException(String msg)
    {
        super(msg);
    }
}

class FactorDemo
{
    // Static method to display factors
    static void displayFactors(int n)
    {
        System.out.println("Factors of " + n + " are:");
        for(int i = 1; i <= n; i++)
        {
            if(n % i == 0)
                System.out.print(i + " ");
        }
    }

    public static void main(String args[])
    {
        Scanner sc = new Scanner(System.in);

        try
        {
            System.out.print("Enter a number: ");
            int num = sc.nextInt();

            // Condition check
            if(num > 1000)
                throw new NumberOutOfRangeException("Number is out of Range");

            // Call static method
            displayFactors(num);
        }
        catch(NumberOutOfRangeException e)
        {
            System.out.println(e.getMessage());
        }
    }
}
