Primitive Data Types and Literals
This chapter provides tutorial notes and example codes on primitive data types and literals. Topics include 8 primitive data types; storage size of each data type; format rules on source code literals for each data type; example Java programs on primitive types.

- Java supports 8 primitive data types: byte, short, int, long, char, float, double, boolean.
- "byte", "short", "int" and "long" can be used to represent signed integers in different ranges.
- Default data type is "int" for integer literals.
- Default data type is "double" for floating-point literals.
- Hex floating-point literals can be used to represent
a particular floating-point value accurately.
