我需要在方法末尾傳遞字符串，以便直接在主方法中打印字符串，但是當(dāng)我在下面這樣做時(shí)，我只收到這個(gè) [Ljava.lang.String;@135fbaa4public static String businessLogic(String[] words) {    for (String word : words) {        char[] arrayWordInChar = word.toCharArray();        int wordLength = word.length();        for (int i = 0, j = wordLength - 1; i < j; ) {            if (!Character.isAlphabetic(arrayWordInChar[i]))                i++;            else if (!Character.isAlphabetic(arrayWordInChar[j]))                j--;            else                swapLetters(arrayWordInChar, i++, j--);        }        arrayWordInChar.toString();    }    return Arrays.toString(words);}public class Main {public static void main(String[] args) {    Scanner scanner = new Scanner(System.in);    String[] words = scanner.nextLine().split(" ");        businessLogic(words);        System.out.println(words);}}這個(gè)問(wèn)題我已經(jīng)困惑了快兩天了，請(qǐng)問(wèn)是什么問(wèn)題呢？
