Answer 1

1. Which method is correct to access the value of count?

Correct answer is B) public static int getCount() {return count;}

Explaination: Public access modifier will allow to access value of count outside the class as well with return as count.

Return statement always as return keyword and value to be returned.

2. How can you print the value of count?

Correct answer is A) System.out.println(a.getCount());

Explaination: We have created object a of class Person inside class SomeOtherClass. getCount() method is of class Person so we can access it by object a of class Person a.getCount() in this way.
