at line 18 we define a class which named it Dog and its assigning data must be String. inside that we define an attribute which named it name. so we create 3 object in main class for 3 dogs and under them we assign an attribute to each of them. Dog dog1 = new Dod(); dog1.name = "Max"; and so on.

Why is this different than the cat exercise?

Short answer, the Cat has no added information about it that we need to display. The long aswer is: Basicly what is happening here is that the first object

Dog dog1 = new Dog();
dog1.name = "Max";

Is making an object called Dog, makes a reference to the Dog class with

= new Dog();

The Dog class is declared that the name is a String

public String name;

All you need to do now is to call whatever dogreference you like to get the name with

System.out.println(dog1.name);

Let's say you also wanted to include age, then you could add to the Dog class

int age;

Let's say we add the age to the dog1 reference and because we know it's a number and we already decladed that it's of the type int, we only have to type

dog1.age = 12;

Now if we want to display the name and the age of dog1 we can call that by typing

System.out.println("The name of the first dog is: " + dog1.name
+ " and the age is: " + dog1.age);
//The output would be

The name of the first dog is: Max and the age is: 12 Declaring everything in the Dog class, makes it much easier to assign whatever you want. So by making classes for Car, Cat, Dog, Airplane, Hamburger or w/e makes things easier when you want to call it in the main method.

solution

In conditions, they said that each Dog obj must have a name U created given obj name as obj So the code is Dog dog1=new Dog(); dog1.name="Max"; same for others
