Given the following array data, answer the following questions:int[ ] arr = {8,4,5,7,2,6,9,1}   How many checks (i.e., iterations through the loop) would be needed to return the index of the value 6 (or -1 if it can’t be found) using Linear Search? The Linear Search Algorithm is given, for reference:

Using Bubble Sort, show the state of the array at the end of each iteration through the outer loop (i.e., after each full time/sweep/traversal through the array using the inner loop) until the algorithm is complete/finished. The Bubble Sort Algorithm is given, for reference:

Assume we wanted to include a new specialized class called “Doctor” that inherited from MedicalStaff. Select all the types that Doctor would be through Polymorphism (i.e., which data types would return true if you performed “Doctor instanceof “).

The “throws” reserved word is used to generate/create a new Exception.

Refactor (i.e., recode/rewrite) the constructors for both the Patient and MedicalStaff classes so they are valid now that they are inheriting from User

When instantiating/create a class that uses generics, ANY non-primitive type can be used for the generics (i.e., it would be valid to give ANY non-primitive type for ArrayList’s generics).

How many checks (i.e., iterations through the loop) would be needed to return the index of the value 3 (or -1 if it can’t be found) using Linear Search?
