Program:

import java.util.Scanner;

public class Overflow {

    public static void main(String[] args) {

        int buff, test, count;

        Scanner sc = new Scanner(System.in);

        System.out.println("Enter Buffer Size:");

        buff = sc.nextInt();

        int[] tests = new int[buff];

        System.out.println("Enter Number of Elements:");

        count = sc.nextInt();

        System.out.println("Enter Numbers:");

        try {

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

                test = sc.nextInt();

                tests[i] = test;

            }

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

                System.out.println(tests[i]);

            }

        } catch (ArrayIndexOutOfBoundsException ae) {

            System.out.println("Buffer Overflow");

        }

    }

}

Output:
run:
Enter Buffer Size:
5
Enter Number of Elements:
6
Enter Numbers:
23 32 32 32 32 23
