In the Java programming language, fields, constructors, methods, and classes can be marked withaccess modifiers. In this tutorial, we’ll talk about theprivateaccess modifier in Java. 2.

Public is the most well known of the Java keywords. Public is also the easiest of the Java access modifiers because of its nature. A variable or method that is public means that any class can access it. This is useful for when the variable should be accessible by your entire application....

Java's public access modifier is the least protective of the modifiers, and should be used only when you absolutely know that you want anything and everything to be allowed access to the methods and variables. Private Private helps to encapsulate your methods and variables most effectively. What...
