Typecode static properties have the TC_ Prefix, just like from Gosu

In the 8.0 Java API, the static properties on a typelist that represent a typecode have the TC_ prefix, just like from Gosu. However, to actually work with the typecode, you must call the get method on the static property to get the appropriate typecode object. For example:

LossType.TC_OPEN.get()
