How to make sure that when you enter the word "Man" in the console, the code in this if is executed?

Question

Java

System.out.println("Введите ваш пол");
        
         if (?? ) {
            double d = (x - y) * z;
            System.out.println("Вес=" + d);
        }

How can I make the code specified in if () be executed when the word "Man" is entered in the console?

Greetings!
Here is a simple example:

public class Main {
  
  public static void main(String ... args) {
    Scanner scanner = new Scanner(System.in);
    System.out.println("Введите ваш пол:");
    String gender = sc.nextLine();
    if(gender.equals("Мужчина")) {
      double d = (x - y) * z;
      System.out.println("Вес=" + d);
    }
  }

}
