Кто-нибудь может подсказать, почему выдает ошибку?

import java.util.Scanner;
public class ChosenOne{
public static void main(String[] args) {
System.out.print("Enter your name, please: ");
Scanner sc = sc.nextLine();
if (b = "HarryPotter"){
Incompatible types. String can't be converted to boolean

System.out.println("You are" + "is a Harry Potter");
} else {
System.out.println("Dear" + "b" + "b" + "b" + "b" + "is a Harry Potter. " + "b" + "b" + "You are not Harry Potter");
} else {
System.out.println("Dear" + "You are not Harry Potter");
} else {
System.out.println("Dear" + "b" + "is a Harry Potter. " + "Please, go fuck yourself");
}
}
}
}
}
}
}
}
}}}}}}}}}}}}}}}
