[JAVA]Need fix for an array
I'm making a code that simulates the card game "war," for i do not want to simulate anything harder. this is hard enough D:
Anyway, i need a relevant ArrayList example, because the user's deck size (currently array) will need to be constantly shortened and lengthened.
Here is the code, if it matters.
Code:
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.Random;
public class mainClass {
public static int[] deck = {2, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 4,
5, 5, 5, 5, 6, 6, 6, 6, 7, 7, 7, 7, 8, 8, 8, 8, 9, 9, 9, 9, 10, 10, 10, 10,
10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 10, 11, 11, 11, 11 }; //2, 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A
public static int[] firstUsersPile = {};
public static int[] secondUsersPile = {}; //Robot pile
public static String userName;
public static Random randomCard = new Random();
public static void main(String[] args) {
try {
BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
System.out.println("Welcome to war! The deck is being shuffled"); //lie. it's random anyway.
System.out.println("Please enter your name: ");
if ((userName = in.readLine()) != null) {
System.out.println("Thank you, " + userName);
int deckUsed; //Initialize
for (deckUsed=0;deckUsed<=deck.length;deckUsed++) {
System.out.println(randomCard.nextInt(deck.length + 1)); //Ignore this part, it will be fixed once "Cards" can be removed from the deck,
//Currently, it just prints a random number from 0-52. Just to simulate whether i need to nullify cards that have been placed in a user's deck
}
} //End IF
}
catch (IOException IOEx) {
System.err.println("Error has occurred.\nApplication exiting...");
System.exit(1);
}
}
/*
* This is a simulation of the card game "War," in which each person has 26 cards, and draws, the larger card wins.
* The winner of each 'round' get's the opponent's card, and puts the card on the bottom of their deck. Ties
* usually cause 3 cards to be drawn, the third card being the determining factor, and if another tie it continues,
* but for the sake of keeping time in priority, each person keeps the card. Even though games can continue ENDLESSLY
* because of this, oh well.
