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 largest element in the given array?

1. public class LargestElement {
2. public static void main(String[] args) {
3. int a[] = { 3, 4, 1, 5, 0, -10 };
4. int max = Integer.MIN_VALUE;  //-2147483648
5. for (int i = 0; i < a.length; i++) {
6. if (a[i] > max) {
7. max = a[i];
8. }
9. }
10. System.out.println("max: " + max);
11. }
12. }

Output:

max: 5
