Java language implementation of simple shuffle, licensing

In the course of Java learning, the teacher has written a simple bucket landlord shuffle licensing program, which is the program code:

 Packagecom.java.lei.homework;Importjava.util.Arrays;ImportJava.util.Random; Public classPokergame {//1. Create an array to store poker    Staticstring[] Pokers =Newstring[54];  Public Static voidMain (string[] args) {//2. Create a card with all the cards assigned to the arrayPokers =Newpoker (); //3. Shuffle here the argument pokers is a newly generated pokers after creating the cardstring[] Pokers2 =Upsetpoker (pokers); //4. LicensingSendpoker (pokers2);} //How to create a card     Public Staticstring[] Newpoker () {//1. Define a suit arraystring[] colors = {"Red peach", "spades", "Plum Blossom", "square piece"}; //2. Define the face arraystring[] numbers = {"A", "2", "3", "4", "5", "6", "7", "8", "9", "Ten", "J", "Q", "K"}; //3. Define the KingString[] Kings = {"King", "Xiao Wang"}; //4. Using loops to store cards in the pokers array               intindex = 0;  for(inti = 0; i < numbers.length; i + +) {             for(intj = 0; J < Colors.length; J + +) {Pokers[index+ +] = Colors[j] +Numbers[i]; }        }                //5. Size King copy into Pokers arraySystem.arraycopy (Kings, 0, Pokers, index, 2); //6. Output CardSystem.out.println ("Existing deck of Cards" + arrays.tostring (pokers) + "\ n"); returnpokers; }        //Shuffle The way     Public Staticstring[] Upsetpoker (string[] array) {//1. Define a new array to store the washed cardsstring[] Newpokers =NewString[pokers.length]; //2. Define an array to identify the cards that are randomly removed        Boolean[] Mark =New Boolean[Pokers.length]; //3. Shuffle         for(inti = 0; i < pokers.length; i + +) {            //A. Creating a random numberRandom rd =NewRandom (); //B. Obtaining a subscript for a random number            intindex =Rd.nextint (pokers.length); //C. Judging the identity            if(Mark[index] = =false) {                //D. Store the non-washed cards in newpokersNewpokers[i] =Pokers[index]; //E. Modify the logo, the washed card is marked true}Else{i--;//the random number to fetch is a washed card, then re-fetch once            }        }                //copy of the card inside the newpokers to the array pokersPokers =arrays.copyof (Newpokers, newpokers.length); System.out.println ("Washed cards:" + arrays.tostring (newpokers) + "\ n"); returnnewpokers; }        //the method of licensing     Public Static voidSendpoker (string[] array) {//1. Define the player and hole cards arraystring[] One =NewString[0]; String[]=NewString[0]; String[] Three=NewString[0]; String[] Underpoker=NewString[3]; //2. Cycle for Licensing         for(inti = 0; i < pokers.length-3; i++) {            if(i% 3 = = 0) { One= Arrays.copyof (One, one.length+1); One[one.length-1] =Pokers[i]; }Else if(i% 3 = = 1) {= Arrays.copyof (both, two.length+1); Two[two.length-1] =Pokers[i]; }Else if(i% 3 = = 2) {Three= Arrays.copyof (Three, three.length+1); Three[three.length-1] =Pokers[i]; }} system.arraycopy (Pokers, Pokers.length-3, Underpoker, 0, 3); System.out.println ("Player 1:" +arrays.tostring (one)); System.out.println ("Player 2:" +arrays.tostring (both)); System.out.println ("Player 3:" +arrays.tostring (three)); System.out.println ("Hole Card:" +arrays.tostring (Underpoker)); }}
