Computer memory stores arbitrary bit patterns. As with a string of letters, the meaning of a string of bits depends on how it is used. The scheme being used for a particular string of bits is its data type. A data type is:
30
Is a scheme for using bits to represent values.
Values are not just numbers, but any kind of data that a computer can process.
All values in a computer are represented using one data type or another.

It would be awkward if every time you used data you had to invent your own scheme to represent it with bits. There are types of data that are so fundamental that ways to represent them are built into Java. These are the primitive data types. The eight primitive data types are:

Q.
An object is a big block of data. An object may use many bytes of memory.
An object usually consists of many internal pieces.
The data type of an object is called its class.
Many classes are already defined in Java.
A programmer can invent new classes to meet the particular needs of a program. Can the users create objects?
