Write a program to create your own exception types to handle situation specific to your application (Hint: Define a subclass of Exception which itself is a subclass of Throwable).

Program:

import java.util.Scanner;

public class OwnExcep extends Exception {

    public OwnExcep(String s) {

        super(s);

    }

}

class Demo {

    static void find(int arr[], int item) throws OwnExcep {

        boolean flag = false;

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

            if (item == arr[i])

                flag = true;

        }

        if (!flag) {

            throw new OwnExcep("Item Not Found"); // calling constructor of user-defined exception class

        } else {

            System.out.println("Item Found");

        }

    }

    public static void main(String[] args) {

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter A number to find :");

        int a = sc.nextInt();

        sc.close();

        try {

            find(new int[] { 12, 25, 45,67,34,45,6,7,98,23 }, a);

        } catch (OwnExcep i) {

            System.out.println(i);

        }

    }

}

OutPut:

Enter A number to find :

45

Item Found
