我不知道为什么这个java代码没有'；行不通

好吧，我做了一个逃逸房间的程序，光的布尔值不起作用

class Main {
  public static void main(String[] args) {
  System.out.println("Welcome To The Hogwarts Escape Room");
  System.out.println("To Play The Hogwarts Escape Room Press Y");
  Scanner sc = new Scanner(System.in);
  String useranswer = sc.nextLine();
  boolean light = false;
// This is not my entire code but the part that was necessary. 
  System.out.println("Press U to look up");
useranswer = sc.nextLine();
if (usernaswer.equals("U"){
System.out.println(" You look above you and see nothing as the ceiling is too dark to see in.");
    System.out.println("Would you like to: \n Look Closer press A \n Return To Your Original Position press B");
    useranswer = sc.nextLine();
    System.out.println(light);
// this part doesn't work.. I checked and made sure the useranswer was A and the boolean does equal to false.
    if (useranswer.equals("A")&&(light = false)){
      ceilingCloserlightFalse(sc, useranswer, inventory, light);
    }
    else if (useranswer.equals("B")){
      original(sc, useranswer, inventory, light);
    }
// this was the setup to the constructor

public static void ceilingCloserlightFalse(Scanner sc, String useranswer, String [] inventory, boolean light){
    System.out.println("You go closer and see something faintly but cant tell what it is without a light");
    System.out.println("You returned to the original position because there was nothing else to do there.");
    original(sc, useranswer, inventory, light);
    
  }
    
  }
}

好的，我想知道我是否对方法或&&运算符做了错误的操作。我检查以确保useranswer是a，并且我还检查以确保

这里您为变量赋值为false，而不是比较它：

if (useranswer.equals("A")&&(light = false)){
      ceilingCloserlightFalse(sc, useranswer, inventory, light);
    }

---

您想使用

==

，而不是

=

。另外，考虑USER回答可能是NULL，所以您应该做的是代码>“A”。 而不是：

if (useranswer.equals("A")&&(light = false)){
      ceilingCloserlightFalse(sc, useranswer, inventory, light);
}

把你的比较写得像

if (useranswer.equals("A")&&(false = light)){
      ceilingCloserlightFalse(sc, useranswer, inventory, light);
}

---

然后会出现一个编译器错误，指出您使用的是

=

而不是

=

light=false

，您的意思可能是

=

。而且，

usernaswer

看起来像是打字错误。很难说为什么它不起作用，因为你没有说它应该做什么，也没有说它应该做什么。
