Abstraction in Java is the process of hiding internal implementation details and showing only essential functionality to the user. It focuses on what an object does rather than how it does it. An abstraction is something nonspecific, a concept that isn't concrete. It can also refer to the state of mind in which a person is not paying attention to something but is lost in thought or daydreaming. In software, an abstraction provides access while hiding details that otherwise might make access more challenging. [1] It focuses attention on details of greater importance. [2][3] Examples include the abstract data type which separates use from the representation of data [4] and functions that form a call tree that is more general at the base and more specific towards the leaves.
