[Java] How to find min number from an array?

1. Simplest way to find the smallest number

We have Arrays.sort() utility available to sort the elements from an array, using this we can sort the array first, then we can pick the first element to find the smallest element.
Following code shows that

import java.util.Arrays;

public class JavaArrays {

	public static void main(String[] args) {

		int[] numbers = { 22, 456, 97, 4 };
		Arrays.sort(numbers);
		System.out.println("Smallest number from the array: " + numbers[0]);

	}

}

2. Efficient way to find smallest number

In Java you can iterate though an array to find the smallest number of an array.

Following program shows how to do that

public class JavaArrays {

	public static void main(String[] args) {

		int[] numbers = { 22, 456, 97, 4 };

		System.out.println("Smallest number from the array: " + minMumber(numbers));

	}

	static int minMumber(int[] numbers) {
		int min = numbers[0];

		for (int ele : numbers) {
			if (ele < min) {
				min = ele;
			}
		}
		return min;
	}

}
