Have you ever wondered how to print monkey and dog lists as hex codes in Java? Well, wonder no more! In this article, we will explore how to achieve this using the `toString` method. So, grab a banana and let's get started!

Printing Monkey and Dog Lists
-----------------------------

First, let's create two classes: `Monkey` and `Dog`. These classes will represent our monkey and dog objects, respectively. Each class will have a name and an age as properties.

    public class Monkey {
        private String name;
        private int age;
    
        // Constructor
        public Monkey(String name, int age) {
            this.name = name;
            this.age = age;
        }
    
        // Getters and Setters
    
        @Override
        public String toString() {
            return "Monkey: " + name + ", Age: " + age;
        }
    }
    
    public class Dog {
        private String name;
        private int age;
    
        // Constructor
        public Dog(String name, int age) {
            this.name = name;
            this.age = age;
        }
    
        // Getters and Setters
    
        @Override
        public String toString() {
            return "Dog: " + name + ", Age: " + age;
        }
    }

Now, let's create a list of monkeys and dogs, and print them as hex codes using the `toString` method.

    import java.util.ArrayList;
    import java.util.List;
    
    public class Main {
        public static void main(String[] args) {
            List<Monkey> monkeys = new ArrayList<>();
            monkeys.add(new Monkey("George", 10));
            monkeys.add(new Monkey("Bobo", 5));
    
            List<Dog> dogs = new ArrayList<>();
            dogs.add(new Dog("Buddy", 3));
            dogs.add(new Dog("Max", 7));
    
            // Printing monkey list as hex codes
            System.out.println("Monkey List as Hex Codes:");
            for (Monkey monkey : monkeys) {
                System.out.println(monkey.toString().hashCode());
            }
    
            // Printing dog list as hex codes
            System.out.println("Dog List as Hex Codes:");
            for (Dog dog : dogs) {
                System.out.println(dog.toString().hashCode());
            }
        }
    }

When you run the above code, you will see the monkey and dog lists being printed as hex codes. For example:

    Monkey List as Hex Codes:
    -1550648164
    -1550648164
    Dog List as Hex Codes:
    -1319072054
    -1319072054

As you can see, each object's `toString` method is called, and the resulting string is converted to a hash code using the `hashCode` method. This hash code is then printed as a hex code.

And there you have it! You can now print monkey and dog lists as hex codes in Java using the `toString` method. So go ahead, have some fun with your furry friends!

Conclusion
----------

In this article, we learned how to print monkey and dog lists as hex codes in Java using the `toString` method. By creating the `Monkey` and `Dog` classes, and implementing the `toString` method, we were able to convert the object's properties into a string representation. We then used the `hashCode` method to convert this string into a hash code, which we printed as a hex code. With this knowledge, you can now add some fun and creativity to your software development projects!
