Question

In java please Create an immutable class named Card implementing the Comparable interface that will represent a card, have a suit: diamonds - lowest, clubs, hearts, spades - highest) and a rank ( 2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A). The class must have a constructor provided with a suit and rank, and the following methods: toString(), getSuit(), getRank(), print(). Create a static method that will randomly generate a card. A card is less than another either if the suite is lower or if they have the suite, then the rank is lower. Please add comments and a run code output pic please to ensure the code ran please. Thank you

Please upvote, as i have given the exact answer as asked in question. Still in case of any concerns in code, let me know in comments. Thanks!
