Question

Which keyword is used to declare all methods to be accessible to all other classes?

a. public
b. protected
c. private
d. package visibility

Answer 1

The keyword to declare all methods accessible to all other classes is 'public'. It allows methods of a class to be accessed from any other class.

Step-by-step explanation:

The keyword used to declare all methods as accessible to all other classes is public. When a method is declared with the public keyword, it can be accessed by any other class in the program, which is essential for allowing classes to interact with each other. The visibility of methods is controlled using access modifiers, and in contrast to other access modifiers like protected, private, or package visibility (no explicit modifier), the public modifier has the widest scope of accessibility.
