Basic Scalar Types
The basic scalar types are mapped as follows:
| Java type | DLL |
| int | signed 32-bit integer |
| byte | signed 8-bit integer |
| short | signed 16-bit integer |
| long | signed 64-bit integer |
| float | 32-bit float |
| double | 64-bit double |
Note that there is no direct representation of unsigned integer types in Java. Since Java has no unsigned types, use the Java type which is the same size as the integer type you want. For example, the Java int type can be used without loss of representation for the common DWORD (unsigned 32-bit) type.
