Selenium WebDriver with Java - Basics to Advanced and Frameworks - What is Super Keyword?

The video tutorial explains the concept of the 'super' keyword in Java, focusing on its usage in accessing parent class variables when there is a name collision with child class variables. It begins with creating a parent and child class, demonstrating inheritance using the 'extends' keyword. The tutorial highlights how Java gives preference to local variables in the child class over inherited ones. It then introduces the 'super' keyword to access parent class variables explicitly, resolving conflicts when both classes have variables with the same name.

• When there is a name collision
