Objects have states and behaviors. Example: A dog has states - color, name, breed as well as behaviors – wagging the tail, barking, eating. An object is an instance of a class.

Class − A class can be defined as a template/blueprint that describes the behavior/state that the object of its type support.

Documentation for java code is often generated using javadoc. Javadoc was created by Sun Microsystems for the purpose of generating API documentation in HTML format from java source code. Using the HTML format gives the convenience of being able to hyperlink related documents together.

Classes and Objects are used to to make your code more efficient and less repetitive by grouping similar tasks.

A class is used to define the actions and data structure used to build objects. The objects are then built using this predefined structure.

Pipe operators, available in magrittr, dplyr, and other R packages, process a data-object using a sequence of operations by passing the result of one step as input for the next step using infix-operators rather than the more typical R method of nested function calls.

Note that the intended aim of pipe operators is to increase human readability of written code. See Remarks section for performance considerations.
