[Java] How to get a random element from an array?

Using java.util.Random we can generate a random number of length less than Array size and we can use that as index to pick a random element from array. Following code shows how to do that

import java.util.Random;

public class JavaArrays {
	public static void main(String[] args) {
		String[] colors = { "blue", "red", "green", "yellow" };
		String randomColor = colors[new Random().nextInt(colors.length)];
		System.out.println(randomColor);
	}
}

Output:

blue
