nThe default scope occurs when you don't specifically assign a scope to a class element. Because many Java developers have no idea what the default scope is for some elements (and using a default scope means that your code isn't documented), it isn't used very often. \
The default methods were introduced to provide backward compatibility so that existing interfaces can use the lambda expressions without implementing the methods in the implementation class. Default methods are also known as defender methods or virtual extension methods.
"Scope" refers to the areas of your program in which certain data is available to you. Any local variable created outside of a method will be unavailable inside of a method.
When we don't use any keyword explicitly, Java will set a default access to a given class, method or property. The default access modifier is also called package-private, which means that all members are visible within the same package but aren't accessible from other packages: package com.
The default scope is package-private. All classes in the same package can access the method/field/class. Package-private is stricter than protected and public scopes, but more permissive than private scope.

Anything defined as package private can be accessed by the class itself, other classes within the same package, but not outside of the package, and not by sub-classes.
See this page for a handy table of access level modifiers...
Without an access modifier, a class member is accessible throughout the package in which it's declared. You can learn more from the Java Language Specification, §6.6.
Members of an interface are always publicly accessible, whether explicitly declared or not.
The default scope is "default". It's weird--see these references for more info.
