CodeHS 7.3.7 JAVA In this exercise, you will create a couple of helper methods for ArrayLists in a class called ArrayListMethods. Create three static methods: print- This method takes an ArrayList as a parameter, and simply prints each value of the ArrayList on a separate line in the console. condense- This method takes an ArrayList as a parameter, and condenses the ArrayList into half the amount of values. While traversing, this method will take the existing value at the index and multiplies the element following to the existing value. For example, if we had an ArrayList that consisted of Doubles [1, 2.5, 2, 3.5], then ArrayListMethods. condense([1, 2.5, 2, 3.5]) would alter the ArrayList to be [2.5, 7]. duplicate- This method takes an ArrayList and duplicates all of the values by adding each value to the end of the ArrayList. For example, ArrayListMethods. duplicate([2.5, 7]) would be [2.5, 7, 2.5, 7]. If done correctly, the methods should work in the ArrayListMethodsTester file.

Problem 3: (hand) write the member function implementations for the class hand, which simulates a hand of 2 cards, into the file hand. cpp. the relative strength of 2 hands are determined by the following rules: • a pair (two cards of the same number) is the strongest hand. • two cards of the same suit is the next strongest hand. • two cards of different numbers and suits is the weakest hand. • within the same kind of hands, the stronger hand is determined by the larger number. • if two hands are of the same kind and the larger numbers are the same, the stronger hand is given by the hand whose smaller number is larger. • if all above fails, the two hands are of equal strength. i. e., all suits are of equal strength. • 2 is the weakest number. an ace is stronger than a king. you are using a single deck of cards. so a hand of a♥a♥ is impossible. here are some examples:
