What is the difference between package private/public protected and private?

Public instance methods: – Use if displaying information or interacting with other classes and/or the client. Private instance methods: – Accessible only from within class scope. … – Use when wanting to compare/interact with other class objects, but don’t want the program or client to have access to them.
What is the main difference between a class and a method?
