当我打算输出Char时，我的Char数组是打印输出的数字

Question

这是我的代码

    Scanner in = new Scanner(new File("words.txt"));
    int choice = 0;
    String str = in.next();
    int FileSize = Integer.parseInt(str);
    char[] wordPlay = new char[100]; 
    System.out.println("Filesize = " + FileSize); 
    int i = 0;
    int count = 0;
    String[] word = new String[FileSize];
    String randomWord;
    Random R = new Random();
    for(i = 0; i < FileSize; i++)
    {
        word[i] = in.next();
        System.out.println("Words = " + word[i]);
    }
    count = R.nextInt(FileSize);
    randomWord = word[count];
    System.out.println("Randomword = "+ randomWord);
    int size = randomWord.length();
    wordPlay = randomWord.toCharArray();
    System.out.print("Random Word in Char =");

    for(i = 0; i <size; i ++)
    {
        System.out.print(+ wordPlay[i] + " ");
    }
    System.out.println(" ");

当它通过循环时它打印出数字但不是疯狂的数字，它们似乎意味着什么，但我无法理解它。

你有一个额外的+。使用：

System.out.print(wordPlay[i] + " ");

+作为一元加号，基本上与负号相反（一元减号）。这会将char强制转换为整数。请参阅§15.15.3（一元加运算符）和§5.6.1（一元数字促销）。
