    }
    System.out.printf("\n");
  }
}

Male.

Explanation

In the above program, we imported the "java.util.Scanner" package to read input from the user. And, created a public class Main. It contains a static method main().

The main() method is an entry point for the program. Here, we read a character from the user using the Scanner class. Then we printed the corresponding gender.
