Question

Write a program in JAVA that asks the user to enter an integer. Store the integers in an array. Allow for up to 10 integers. When the user enters -1, the program should end. Print the number of integers entered as well as the number of times each integer was entered.

Answer 1

import java.util.Scanner;

public class IntegersInput {

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int[] data = new int[10];
        int count = 0;

        for (int i = 0; i < 10; i++) {
            System.out.print("Enter a number(-1 to exit): ");
            data[i] = in.nextInt();
            if (data[i] == -1)
                break;
            ++count;
        }

        System.out.println("Number of integers entered is " + count);
        for (int i = 0; i < count; i++) {
            int c = 0;
            for (int j = 0; j < count; j++) {
                if (data[i] == data[j])
                    ++c;
            }
            System.out.println(data[i] + " was entered " + c + " times");
        }
    }
}
