The usual tricks, like checking for the existence of a class known to be introduced in a given JRE version, looking at various system properties, etc. I suppose you could say that those techniques are more about tolerating different versions of the JRE at runtime because you still have to know in advance what function was introduced when. They can be useful though, especially in cases where you have a problem that can be solved in all JRE versions, but can be solved better in later JRE versions because of new APIs available in the later version. -- Jeffrey E.
