@Pseudonym: Well, technically, it does have char, which is a 16-bit unsigned type. Of course, there are still no unsigned arithmetic instructions in Java bytecode, since any char values are automatically promoted to int (32-bit signed) for arithmetic.

However, basic-type checking of this kind is checking performed by the classloader, so the types can mostly be ignored at run-time. And of course Java bytecode doesn't have unsigned types in the first place. | |
