Need Help! Please!

So I need to create a password application where the user enters a password and a message comes up whether it is correct or incorrect. I did most of it, but I need help on how to add a message where after three incorrect guesses, the message "Access Denied" comes up. How would I do that?

Here is what I have:

import java.util.Scanner;
public class Password {

public static void main(String args[]) {
Scanner input = new Scanner(System.in);
String password;

System.out.println("Enter the password:");
password = input.nextLine();

if(password.equals("Computer Science")){
System.out.println("The password is correct");
}
else{
System.out.println("The password is incorrect");
}

}

}
