The Primitive Types |
---|
Java defines eight primitive types of data: byte, short, int, long, char, float, double, and boolean. |
The primitive types are also commonly referred to as simple types, and both terms will be |
used in this book. These can be put in four groups: |
• Integers This group includes byte, short, int, and long, which are for whole-valued |
signed numbers. |
• Floating-point numbers This group includes float and double, which represent |
numbers with fractional precision. |
• Characters This group includes char, which represents symbols in a character set, |
like letters and numbers. |
• Boolean This group includes boolean, which is a special type for representing |
true/false values. |
