[Q.no.1]

Access modifiers are keywords that can be used to control the visibility of fields, methods, and constructors in a class. The four access modifiers in Java are public, protected, default, and private.

Significance:-
(i) Access specifiers define how the members (attributes and methods) of a class can be accessed. In the example above, the members are public - which means that they can be accessed and modified from outside the code.

(ii) Access Modifiers (Access Specifiers) are keywords that are used in OOP (object-oriented programming) in order to specify the accessibility of the methods, classes, constructors, and other members of the class.
