       Instead, use accessors also called  and modifiers also called .
       Accessors and modifiers are basically public functions used to
       get and set property values of a class. For example, if a class
       has a property name, the following accessor and modifier methods
       can be used Attachment public String return name Mutator public
       void String name name Accessors and modifiers are used to force
       data encapsulation, This is one of the three fundamental pillars
       of object-oriented programming, polymorphism and inheritance
       being the other two. Import packages instead of fully qualified
       names Not only in.
       But in every programming language, the best practice is to
       import a namespace or package in a file instead of repeatedly
       writing fully qualified names to access types Phone Number List

       in those classes. For example, to use
       an object in a program, it is better to first import the package
       into the program and then instantiate the class directly in the
       program rather than writing the fully qualified name again and
       again. To learn more about , take a course on . Reflection is
       one of the most advanced features of any dynamic language such
       as , or , which enables developers to perform sophisticated
       operations.

       It is used to inspect and modify the runtime behavior of objects
       in an application, which means it analyzes the code structure
       and enables programmers to change its expected behavior. In ,
       but the accessibility of fields and methods can be changed. To
       learn more about the basics, take the course on What is Reflex?
       is a set of classes and interfaces encapsulated in that provides
       the following functionality To inspect classes, use interfaces
       and enumerations and retrieve their structures at runtime. Get
       information about fields and methods at runtime. To instantiate
       an object, call its methods and change field values at runtime,
       without prior knowledge of its implementation. How to use
       reflection? is a very powerful feature, but is best avoided if
       there are any alternative solutions to the problem.
