Question

// JavaLanguage

. You need to write a program that asks the user for an array size, and then asks the user to enter that many integers. Your program will then print out the sum , average, largest and smallest of the values in the array.

Answer 1

//SumAverageMinMaxArray.java
import java.util.Random;
import java.util.Scanner;

public class SumAverageMinMaxArray {
    public static int getLowest(int[] numbers){
        int min = Integer.MAX_VALUE;
        for(int i = 0;i<numbers.length;i++){
            if(min > numbers[i]){
                min = numbers[i];
            }
        }
        return min;
    }

    public static int getHighest(int[] numbers){
        int max = Integer.MIN_VALUE;
        for(int i = 0;i<numbers.length;i++){
            if(max < numbers[i]){
                max = numbers[i];
            }
        }
        return max;
    }

    public static int getTotal(int[] iArray){
        int sum = 0;
        for(int i = 0;i<iArray.length;i++){
            if((iArray[i] & 2) > 0 || ((iArray[i] & 4) > 0) || ((iArray[i] & 8) > 0)){
                sum += iArray[i];
            }
        }
        return sum;
    }

    public static double getAverage(int arr[]){
        return 1.0 * getTotal(arr)/arr.length;
    }

    public static void main(String args[]){
        Scanner scan = new Scanner(System.in);
        int size;
        System.out.print("Enter size of array: ");
        size = scan.nextInt();

        int arr[] = new int[size];
        System.out.println("Enter "+size+" integers for array");
        for(int i = 0;i<size;i++){
            arr[i] = scan.nextInt();
        }
        System.out.println();
        System.out.println("Sum = " + getTotal(arr));
        System.out.println("Average = " + getAverage(arr));
        System.out.println("Minimum = " + getLowest(arr));
        System.out.println("Maximum = " + getHighest(arr));
    }
}
