public class Challenge {

    private static boolean isName = false;
    private static String name = new String("John");


    public static void main(String [] args){

        Scanner sc = new Scanner(System.in);

        System.out.println("Guess my name!");

        String guess = sc.nextLine();
        System.out.println("Your guess: "+guess);

    
        if(guess.equals(name)){ 
            isName = true;
        } else {
            System.out.println("Wrong! L Cope");
        }

        System.out.println(isName);

    }
}

Challenge.main(null);

Guess my name!
Your guess: John
true

Homework

Now that you know what boolean expressions are and how to write them, as well as several comparison methods, your task is to write a class that uses either the compareTo or comparator and compare. Then create two instances of these classes and demonstrate using if statements.

BONUS: Create a program that checks if a year is a leap year or not.

Here is how the method should work:

(1) Prompt the user to input any year that they would like
(2) Determine if the year is a leap year or not
(3) Print the necessary dialogue (ex. [year] is/is not a leap year) AND return the value of any boolean(s) used

public class Doggos {
    private String breed;
    private int age;
    public Doggos(String breed, int age) {
        this.age = age;
        this.breed = breed;
    }
    public int compareTo(Doggos other)
    {
        return Integer.compare(this.age, other.age);
    }
    public String getBreed ()
    {
        return breed;
    }

    public static void main(String[] args)
    {
        Doggos dog1 = new Doggos("Beagle", 4);
        Doggos dog2 = new Doggos("Lab", 2);
        if (dog1.compareTo(dog2) < 0)
        {
            System.out.println(dog1.getBreed() + " is younger than " + dog2.getBreed());
        }
        else if (dog1.compareTo(dog2) > 0)
        {
            System.out.println(dog1.getBreed() + " is older than " + dog2.getBreed());
        }
        else
        {
            if (dog1.compareTo(dog2) < 0)
        {
            System.out.println(dog1.getBreed() + " is the same age as " + dog2.getBreed());
        }
        }
    }
}
Doggos.main(null);

Beagle is older than Lab

public class LeapYear {
    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.print("Enter a year: ");
        int year = scanner.nextInt();
        scanner.close();

        boolean isLeapYear = isLeapYear(year);

        System.out.println(year + (isLeapYear ? " is" : " is not") + " a leap year.");

        if (isLeapYear)
        {
            System.out.println("It is a leap year");
        }
        else
        {
            System.out.println("It is not a leap year");
        }
    }

    public static boolean isLeapYear(int year) {
        return (year % 4 == 0 && year % 100 != 0) || (year % 400 == 0);
    }
}
LeapYear.main(null);

Enter a year: 

2024 is a leap year.
It is a leap year

Complete the weird questions below.

Weird questions

!(true)&&(false) = ? what in boolean values?
false
not ((((true and not (false)) ^ false) ^ true) && false) (remember PEMDASNAO!)
not ((((true and true) ^ false) ^ true) && false)
not (((true ^ false) ^ true) && false)
not ((true ^ true) && false)
not (false && false)
not (false)
true
Prove the following: !A * !(B + !C) = !A * (!B * C)
De Morgan’s: !A * (!B * C) = !A * (!B * C)
420 && 66 (Hint, convert to binary, then perform the operation)
110100100 && 1000010
0000000 = 0
1. If you got this one, try 89 OR 42
  1011001 || 101010
  1111011 = 123

For each example, you can use code, but then show your work and how you got it. Please ask questions if you are confused!
