- Write the following method that returns an ArrayList from a set:public static <E> ArrayList<E> setToList(Set<E> s)Code in task3() method by implementing the following sequence using ArrayList. 1. Declare an array list named myList which has the capacity of 10. 2. Add the following numbers: "one", "seven", "five", "three", "eight", "ten". 3. Insert the value "eleven" in between "five" and "three". 4. Print all the elements in the myList 5. Delete the second last element in the myList 6. Print true if myList contains "seven"; false otherwise. Note: Your code should use the appropriate data types.The ArrayList is created using the following syntax: String[] array = {"red", "green", "blue"}; ArrayList list Display all the elements of this list using: a) foreach loop b) foreach method with lambda := new ArrayList(java.util.Arrays.asList(array));
