A data field is a location for a predetermined type of data that — collectively with other data fields — describes the place it is stored . The most common example is a column in a data table that describes the row with which it intersects, and others include class variables in programming languages such as Java.

A field may be either of primitive or reference type. There are eight primitive types: boolean , byte , short , int , long , char , float , and double . A reference type is anything that is a direct or indirect subclass of java.
