What is Super Keyword?

The video tutorial explains the concept of the 'super' keyword in Java, focusing on its role in inheritance. It begins by creating two classes, a parent and a child, and demonstrates how the child class inherits properties from the parent class using the 'extends' keyword. The tutorial highlights the preference of local variables over inherited ones and introduces the 'super' keyword to access parent class variables when there is a naming conflict. The video concludes by showing how to differentiate between parent and child class variables using 'super'.

What is the primary purpose of the 'super' keyword in Java?

• To create a new class

• To access methods of the child class

• To refer to the parent class

• To define a new variable

Which keyword is used in Java to inherit properties from a parent class?

• inherits

• implements

• extends

• super

In the context of inheritance, what happens when a child class has a variable with the same name as a variable in the parent class?

• The parent class variable is always used

• The child class variable is always used

• An error occurs

• The program crashes

What will be printed if a child class variable and a parent class variable have the same name, and the child class variable is accessed?

• The value of the parent class variable

• The value of the child class variable

• An error message

• Nothing will be printed

How can you access a parent class variable when there is a name collision with a child class variable?

• By using the 'super' keyword

• By using the 'parent' keyword

• By using the 'base' keyword

• By using the 'this' keyword

If a child class does not have a variable with the same name as a parent class variable, what happens when the variable is accessed?

• An error occurs

• The program will crash

• The variable is undefined

• The parent class variable is used

When is the 'super' keyword not required in a child class?

• When the child class has more methods

• When the child class is final

• When there is no variable name collision

• When the parent class is abstract
