HangMan删除从数组中猜到的字母

Question

我在编写我的hangman程序时遇到了障碍我帮助删除了我已经正确的字母从这里我的数组中猜到的是我的代码：

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));

                    System.out.println("You got it wrong");

                }

            }

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

    }

    //removes all duplicates from the array

                j++;
            }

            if (i < List.size() - 1) {

            }
        }

        return sb.toString();   


    }

}

你们有任何建议会很棒我没有想法

使用List而不是Array，然后您可以使用list remove（）方法删除项目。
