Extending a class

Question 1

How you can extend a class ?

Answer 1

you can extend a class using the “extends” keyword after the child class name

EXAMPLE :

class Animal { }
class Lion extends Animal { }

Question 2

Give an important thing to remember about the accessibility of public members of a class !

Answer 2

In Java, if you have a public member (field or method) in a public class, it can be accessed from another public class within the same package without explicitly importing the class that contains the member.

The same principle applies for protected and default access members.
