What are the differences of Field, Variable and Parameter in Jasper Reports?

Field: A value from the datasource. e.g. if the datasource is a resultset then this will represents a particular field of a result row.

Variable: A variable inside the report that is used for tasks such as counting (e.g. page number) and etc.

Parameter: A value sent from the java program that calls the jasper file.
