Q3. Driver is static or non static
Ans. 
Driver can be both static and non-static depending on the context of its usage.
• Driver class can be static if it is used to initiate the WebDriver instance in a test automation framework.

• Driver class can be non-static if it is used as an instance variable within a test class.

• Static driver can be accessed directly without creating an object of the class.

• Non-static driver requires an object of the class to be created befo

Q4. Difference between static and non static
Ans. 
Static variables belong to the class itself, while non-static variables belong to instances of the class.
• Static variables are shared among all instances of a class

• Non-static variables are unique to each instance of a class

• Static variables are initialized only once, at the start of the program

• Non-static variables are initialized separately for each instance of the class
