Composite data types:-
Each of the data types above accepts one number, one character, or one state.
Composite, or reference, data types consist of more than a single element.
Composite data types are of two kinds: classes and arrays.
Class and array names start with an upper case letter and are
camel-capitalized (that is, the first letter of each natural word is capitalized within the name,
for instance, NameOfClass).
A class is a complete and coherent piece of code that defines a logically unified set of objects and their behavior. For more information on classes,
see Chapter 6, “Object-oriented programming in Java.”
Any class can be used as a data type once it has been created and imported into the program. Because the String class is the class most often used as a data type,
we will focus on it in this chapter.
