Question

我不断在这一行收到错误消息“identifyyer expected”：hk.guess（charToGuess）; 我需要做些什么才能纠正这个问题？

我正在创建一个简单的Hangman游戏，它给了我很多麻烦。我是编程新手，我开始对这个项目感到非常沮丧。

    import java.util.Random;
    import java.util.Scanner;
    import java.util.*;

    hangmanSession.play();
    }

    private int triesNumber = 7;
    hiddenKeyword hk = new HiddenKeyword();
    hk.guess(charToGuess);
    private void printState() {
    System.out.print( "Hidden word : " );
    hiddenKeyword.print();
    System.out.print( "Tries left: " + triesNumber + "\n<guess letter:>" );
    }

    public void play() {
    boolean bool = true;
    while( true ) {
    bool = true;
    printState();
    System.out.println( "Try again, you've already used that letter " + char.class );
    bool = false;
    }
    if( bool ) {
    if( hiddenKeyword.guess( char.class ) ) {
    System.out.println( "YAY! you have found letter! " + ch );
    }
    else {
    triesNumber--;
    }
    if( triesNumber < 1 )
    gameOver();

    if( hiddenKeyword.found() )
    congratulations();
    }

请记住，作为Java的经验法则，类可能只包含字段和方法。语句（除了那些将字段初始化为默认值的语句）只能写入方法内。

考虑到上述情况，问题在于您只是在类中调用方法（hk.guess(charToGuess)），而不是在任何方法内部，并且该语句不是字段初始值设定项。
