Java doesn't support unsigned (primative) data types, but I guess you can create a class that does something similar.

The only unsigned data type is the "char" type, but that is not really for numbers.

All the primitve data types are signed in Java. There's one exception the char. Maybe that is exactly what you need:

There is a manual for the predecessor of the Java language here. Look at the top left corner of page 8.
