如何检查两个字符串是否为字母表？

Question

以下是我的项目的细节:
字谜：这个项目的目的是创建一个游戏，在这个游戏中，用户可以看到一个单词的字谜，并且必须在有限的尝试次数内猜出正确的单词。项目特点：

null

import java.util.Arrays;
import java.io.ByteArrayOutputStream;
import java.io.PrintStream;
import java.io.*;
import java.util.Scanner;
import java.util.*;

public class main {
    String A = "words[index]";

    static boolean isAnagram(String A, String B) {
        if (A.length() != B.length()) {
            return false;
        } else {
            char a[] = A.toLowerCase().toCharArray();
            char b[] = A.toLowerCase().toCharArray();

            Arrays.sort(a);
            Arrays.sort(b);
            String sortedA = String.valueOf(a);
            String sortedB = String.valueOf(B);
            if (sortedA.equals(sortedB)) {
            }
        }
        return false;
    }

    public static void main(String[] args) {
        String[] words = {"Rat", "Car", "Below", "Taste", "Cried", "Study", "Thing", "Chin"};
        Random random = new Random();
        int index = random.nextInt(words.length);
        System.out.println("The given word is: " + words[index]);

        Scanner sc = new Scanner(System.in);
        String B = sc.next();
        if (isAnagram(String A, String B)) {
            System.out.println("not an angram");
        } else {
            System.out.println("Sucess");
        }
    }
}

您可以从这些字符串中获取两个字符数组，对它们进行排序，然后检查这些数组是否彼此相等。

/**
 * @param a first string.
 * @param b second string.
 * @return whether two strings are case insensitive anagrams of each other.
 */
static boolean isAnagram(String a, String b) {
    // invalid incoming data
    if (a == null || b == null
            || a.length() != b.length()) return false;
    return Arrays.equals(
            a.toLowerCase().codePoints().sorted().toArray(),
            b.toLowerCase().codePoints().sorted().toArray());
}

public static void main(String[] args) {
    System.out.println(isAnagram("Study", "dusty")); // true
    System.out.println(isAnagram("door", "rooD"));   // true
    System.out.println(isAnagram("door", "root"));   // false
}
