How To Shuffle an Array
Randomly change the order of elements in an array using Collections.shuffle() :
Example
import java.util.Arrays;
import java.util.Collections;
import java.util.List;
public class Main {
public static void main(String[] args) {
String[] fruits = {"Apple", "Banana", "Cherry", "Mango"};
List<String> list = Arrays.asList(fruits);
Collections.shuffle(list);
System.out.println(list);
}
}
