What is Dependency and how it maps into a Java class

A Dependency relationship means when a class consumes/uses methods or variables from other class(supplier).So a change to supplier class affects the consumer class as well.Here supplier is indepenedent of any changes being made to consumer classs.

In UML class diagrams, a dependency relationship connector appears as a dashed line with an open arrow that points from the consumer class to the supplier class. A dependency relationship means an "import" statement.
