the "Old Maid" card game In order to do our impler entation of the card gaue, we need to use a Java valent for Python's lists. We are going to use array As you know, one limitation with Java arrays is that they are offixed size. We will soon see alternatives that can be used when the number of elements to store is not known in advance, but for this game, it hrns ont that the maximum number of cards in any deck is known: there are only 51 cards in this game. so we can use arrays of size 51. aud we are sure that they will always be large enough to hold as mauy cards as we could possibly have in any one deck. Having an array large enough eusures that we will be able to add and remove from that array without having to worry about overflows. However, there is direct way to know how mauy elements are in the array currently. order to address this problem we will have to maintain an additional cointer for each nt our arrays. These counters record the enrrent her ot elements in the array (from 0 to 5 thus). To facilitate our tasks, a utility class is provided. ArrayStrings lools. It can do a few basic things on our arrays such as sorting them. shuffling them etc. A detailed description of the classes can be found here Al 24-javaExplanation / Answer
