Finding smallest value from array in java

Rashed Hasan :

I am trying to get the sum, average, max and min value from user input in array. sum, average and max is giving the correct output. But min value is not working. Where am I doing wrong would someone help me please to find out?

import java.util.Scanner;

public class minMaxSumAverage {
    public static void main(String args[]) {
        int n, sum = 0, max, min;
        double average = 0;

        Scanner s = new Scanner(System.in);
        System.out.println("Enter elements you want to input in array: ");
        n = s.nextInt();
        int a[] = new int[n];
        max = a[0];
        min = a[0];
        System.out.println("Enter all the elements:");
        for (int i = 0; i < n; i++) {
            a[i] = s.nextInt();
            sum += a[i];
            average = (double) sum/a.length;
            if (a[i] > max) {
                max = a[i];
            }
            if (a[i] < min) {
                min = a[i];
            }
        }
        System.out.println("Sum is: " + sum);
        System.out.println("Average is: " + average);
        System.out.println("Max is: " + max);
        System.out.println("Min is: " + min);
    }
}

Output:

Enter elements you want to input in array: 
5
Enter all the elements:
25
5
10
6
4
Sum is: 50
Average is: 10.0
Max is: 25
Min is: 0

Min value should be 4.

I have updated you code. Please check following code to get min value from all element list.

Input :

Enter elements you want to input in array:

5

Enter all the elements:

25

5

10

6

4

Output :

Sum is: 50

Average is: 10.0

Max is: 25

Min is: 4
