24.2. Built In Datatypes

These are the built in atomic types. You can change them if you wish. However this is not good practice.

All these can be found in the java.lang subpackage of the main model.


You should be aware that these are Java datatypes. They are not mandated by the UML standard.

These are the standard datatypes. For their definition refer to the Java standard.


void is not strictly speaking a type, but the absence of type. ArgoUML knows about void and allows it as an option where a datatype may be selected.
