Man子手從數組中刪除猜出的字母

Question

我在編寫hangman程序時遇到了障礙，可以幫助刪除數組中已經正確猜出的字母，這是我的代碼：

import java.nio.charset.Charset;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.Collection;
import java.util.HashSet;
import java.util.Random;
import java.util.Scanner;
public class Game {
    public Game(){

        start();

    }

    public static void start()
    {
        Scanner scan = new Scanner(System.in);
        Random rand = new Random();
        String [] Words = {"Dog","cat","Food","Bacon","Turkey","hood","poo","Good","look"};//initializes the array
        String RandomWord = Words[rand.nextInt(Words.length)];//picks a random word from the char array and stores it in a variabe
        char [] array = RandomWord.toCharArray();//converts the randomly generated word from the array into a char array
        int i = 0;//counter
        char input = 0;
        int WinCounter = 0;//counts the number of wins
        System.out.println("You have a "+RandomWord.length()+" letter word "+RandomWord);
        int tries = 20;
        int wrongCounter = 0;
        ArrayList<Character> list = new ArrayList<Character>();

        while(i<tries){

            i++;

            hangMan(wrongCounter);


            System.out.println("Guess a letter : ");
            input = scan.next().charAt(0);
            list.add(input);
            System.out.println("Guessed Letters are : "+guessedLetters(input,list));

            for(int j = 0; j<noDuplicates(array).length;j++){

                if(findCorrect(array,input, list)+removeCaseSensitive(array,input)>0){
                    j++;

                    System.out.println("You got it right");
                    //System.out.println(noRepeat(list,input));
                    WinCounter++;
                    break;

                }
                else if(!(input ==noDuplicates(array)[j])){

                    System.out.println("You got it wrong");
                    //System.out.println(noRepeat(list,input));
                    wrongCounter++;
                    break;


                }

            }
            if(WinCounter == noDuplicates(array).length)//tests to see if the player won
            {
                System.out.println("You have Won!");
                break;
            }
            else if(hangMan(wrongCounter)){
                break;
            }
        }

        System.out.println();
    }

    public static boolean hangMan(int wrongCounter) {
        boolean isOver= false;
        System.out.println("------------|");
        switch(wrongCounter){
        case 1:
            System.out.println("|           O");
            break;

            System.out.println();
            System.out.println("|          / \\");
            System.out.println("You lost");
            isOver = true;
            break;
        }
        for(int i = 0;i<7;i++)
            System.out.println("|");
        return isOver;

    }

    //removes all duplicates from the array
    private static char[] noDuplicates(char[] a) {
        HashSet<Integer> keys = new HashSet<Integer>();
        char[] result = new char[a.length];
        int j = 0;
        for (int i = 0 ; i < a.length; i++) {

            if (keys.add((int) a[i])) {
                result[j] = a[i];
                j++;
            }
        }
        return Arrays.copyOf(result, j);
    }

    }

            sb.append(List.get(i));
            if (i < List.size() - 1) {
                sb.append(" ");
            }
        }

        return sb.toString();   


    }

}

你們有什么建議都很棒，我沒主意了

Answer 1

使用列表而不是數組，然后可以使用列表remove（）方法刪除項目。
