Can you please explain this java code in details.

$//$ Parent class

class Animal $\{$

private String name;

private int age;

$//$ Constructor

public Animal$($String name, int age$)\{$

this.name $=$ name;

this.age $=$ age;

$\}$

$//$ Encapsulation $-$ Getters and Setters

public String getName$()\{$

return name;

$\}$

public void setName$($String name$)\{$

this.name $=$ name;

$\}$

public int getAge$()\{$

return age;

$\}$

public void setAge$($int age$)\{$

this.age $=$ age;

$\}$

$//$ Abstraction $-$ Abstract method

public void makeSound$()\{$

System.out.println$("$Animal makes a sound"$)$;

$\}$

$\}$

$//$ Child class inheriting from Animal

class Dog extends Animal $\{$

$//$ Constructor

public Dog$($String name, int age$)\{$

super$($name$,$ age$)$;

$\}$

$//$ Polymorphism $-$ Overriding method

@Override

public void makeSound$()\{$

System.out.println$("$Dog barks"$)$;

$\}$

$\}$

public class Main $\{$

public static void main$($String$[]$ args$)\{$

$//$ Creating objects

Animal animal $=$ new Animal$("$Generic Animal", $5)$;

Dog dog $=$ new Dog$("$Buddy$",3)$;

$//$ Accessing fields through encapsulation

System.out.println$("$Animal: $"+$ animal.getName$()+",$ Age: $"+$ animal.getAge$())$;

System.out.println$("$Dog: $"+$ dog.getName$()+",$ Age: $"+$ dog.getAge$())$;

$//$ Polymorphism $-$ calling overridden method

animal.makeSound$()$; $//$ Output: Animal makes a sound

dog.makeSound$()$; $//$ Output: Dog barks
