我无法理解如何从char数组中删除一个字母，这是我的代码
import java.util.Random;
import java.util.Scanner;
public class Main {
public static void main(String [] args)
{
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"};
String RandomWord = Words[rand.nextInt(Words.length)];
char [] array = RandomWord.toCharArray();
boolean [] parrallelArray = new boolean[array.length];
int i = 0;
int placeholder = 0;
System.out.println(findUniqueLetters(array));
char input = 0;
while(i<findUniqueLetters(array)){
i++;
System.out.println("You have a "+RandomWord.length()+" Word "+RandomWord);
System.out.println("Guess a letter : ");
input = scan.next().charAt(0);
for(int j = placeholder; j<array.length;j++){
if(input == array[j]){
j++;
placeholder = j;
System.out.println("You got it right");
break;
}
else if(!(input ==array[j])){
j++;
placeholder = j;
System.out.println("You got it wrong");
break;
}
}
}
System.out.println("You have wasted all your tries!");
}
public static int findUniqueLetters(char [] a){
int Unique = 1;
for(int i = 1; i<a.length;i++){
if(!(a[i] == a[i-1])){
Unique++;
}
}
return Unique;
}
}
是否有其他方法可以执行此操作或删除它是唯一的方法吗？ 我试图用数组中的非重复字母切换数组中的重复字母，但这只适用于某些单词。
