How will you find smallest element in an array?

Problem statement:
Given an array of positive or negative integer. How will you write an algorithm to find out the smallest element in the given array?

1. public class SmallestElement {
2. public static void main(String[] args) {
3. int a[] = { 3, 4, 1, 5, 0, -10, -40 };
4. int min = Integer.MAX_VALUE; // 2147483647
5. for (int i = 0; i < a.length; i++) {
6. if (a[i] < min) {
7. min = a[i];
8. }
9. }
10. System.out.println("min: " + min);
11. }
12. }

Output:

min: -40
