Question
Which of the following is used for implementing inheritance through class?
Solution
The correct answer is "extends" keyword. Here are the steps to implement inheritance through class:
- Define the parent class: This is the class that will be inherited from. It contains the properties and methods that you want to be available in the child class.
public class ParentClass {
// properties and methods
}
- Define the child class: This is the class that will inherit from the parent class. It is defined using the "extends" keyword followed by the name of the parent class.
public class ChildClass extends ParentClass {
// additional properties and methods
}
- Now, the child class has access to all the properties and methods of the parent class. You can also add additional properties and methods in the child class.
ChildClass child = new ChildClass();
child.parentMethod(); // method from ParentClass
child.childMethod(); // method from ChildClass
This is how inheritance is implemented in Java through class using the "extends" keyword.
