Can a variable hold more than one value Java?

A variable holds more than one value if you declare it to be of a composite data type. Composite Data Types include structures, arrays, and classes. A variable of a composite data type can hold a combination of elementary data types and other composite types. Structures and classes can hold code as well as data.
