Solution

The method used to shuffle the elements of an ArrayList in Java is d. Collections.shuffle().

Here is a step by step guide on how to use it:

  1. First, you need to import the Collections module in your Java program. You can do this by adding the following line at the top of your program: import java.util.Collections;

  2. Next, create an ArrayList. For example: ArrayList<String> list = new ArrayList<String>();

  3. Add some elements to your ArrayList. For example:

list.add("Element1");
list.add("Element2");
list.add("Element3");

  1. Now you can shuffle the elements of the ArrayList using the Collections.shuffle() method. Like this: Collections.shuffle(list);

  2. If you print out the elements of the ArrayList, you will see that their order has been randomly shuffled. For example:

for(String str: list){
   System.out.println(str);
}

This will print out the elements of the ArrayList in a random order.
