Inheritance in Java

Inheritance in Java

• Making another class from the existing class is known as inheritance.
• Inheritance is utilized to accomplish dynamic official and reusability.
• The class which is acquired is known as the superclass or parent class and the class got from the parent class is known as a subclass or youngster class.
• Inheritance is executed utilizing broadens catchphrase.

class parent_class_name extends child_class_name
{
                //body
}   

• Simply investigate sentence structure.
• Every one of the properties of parent class come to kid class in the event that they are not private.

• A model about how inheritance is executed in java is given beneath.

class parent
{
                String
name=”Mark”;
}
class child extends parent
{
                void
show()
                {
                                System.out.println(name);
                }
                public
static void main(String…s)
                {
                                child
c=new child();
                                c.show();
                }
}

• In the above model variable name is default along these lines it is open in youngster class.
• In the event that we make the name as private at that point, it will show mistake like “name has private access in the parent”.

Sorts of Inheritance in Java

• There are three sorts of inheritance in java: single, staggered and various levelled inheritance.
• In java, numerous inheritance isn’t upheld by class. Numerous inheritance can be actualized by Interface, later on, we will talk about it.

Why numerous inheritance isn’t upheld in java?

• So as to diminish the multifaceted nature and uncertainty, numerous inheritance isn’t bolstered in java.
• Consider a circumstance where we have three classes A, B and C. Class C acquire class An and B. On the off chance that classes An and B have a strategy with the same model and when we call this technique in class C then it will cause vagueness in light of the fact that the compiler will be befuddled that whether technique from class An is called or strategy from class, B is called.
