Java has four integer types:
All of these are signed, so they have both positive and negative values.
Java does not support unsigned, positive-only integers.
The width and ranges of these integer types vary widely, as shown in this table:
| Name | Width | Range |
|---|---|---|
| long | 64 | -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 |
| int | 32 | -2,147,483,648 to 2,147,483,647 |
| short | 16 | -32,768 to 32,767 |
| byte | 8 | -128 to 127 |
