JAVA Programming

Implement the class DataProcess and prompt a user to enter 5 integer numbers. Once The program should output the average, largest, and smallest of 5 numbers.

You must implement the methods listed below in your program.

static float getAverage(int[] data) {...}

static int getLargest(int[] data) {...}

static int getSmallest(int[] data) {...}

Answer 1

import java.util.Scanner;

public class DataProcess {

    static float getAverage(int[] data) {
        float total = 0;
        for (int i = 0; i < data.length; i++) {
            total += data[i];
        }
        return total / data.length;
    }

    static int getLargest(int[] data) {
        int max = data[0];
        for (int i = 0; i < data.length; i++) {
            if (data[i] > max)
                max = data[i];
        }
        return max;
    }

    static int getSmallest(int[] data) {
        int min = data[0];
        for (int i = 0; i < data.length; i++) {
            if (data[i] < min)
                min = data[i];
        }
        return min;
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        System.out.print("Enter 5 numbers: ");
        int[] data = new int[5];
        for (int i = 0; i < data.length; i++) {
            data[i] = in.nextInt();
        }
        System.out.println("Average: " + getAverage(data));
        System.out.println("Largest: " + getLargest(data));
        System.out.println("Smallest: " + getSmallest(data));
    }
}
