Answer 2

In a Public class are data and function directly accessible outside the class

Explanation:

• 'Public' is a keyword which acknowledges a member's access as 'public'. 'Public' members are always accessible to all other 'classes'. It implies that any other 'class' may have access to a 'public' field or method. Additionally, other 'classes' can change 'public' fields except the field is declared 'final'.
• The best approach is to give the field's 'private' access and restrict 'public' access to only the set of 'methods' and 'final' fields that define the class 'public' constants.
