How do I get the class of a parameterized type in Java without instantiating it?

So say need to pass in the class that represents LinkedList<Path>: java.lang.Class<java.util.LinkedList<java.nio.file.Path>>

without creating one and then using .getClass() ?

FindBugs is bitching at me that this is the only reason I create the object, and the IDE is telling me I can't pass a value of a parameterized type.

Thanks!

What do you mean “pass in?” Are you making a linked list? Or is it a method param? – Jacob B. Apr 13 '18 at 23:25

Can you show actual code so we can see what are you trying to do? – FilipRistic Apr 13 '18 at 23:26

The basic answer is you can't. But this look like an [XY Problem](http://xyproblem.info/). Please explain your goal. – shmosel Apr 13 '18 at 23:27
Could you give a proper example ? – NoDataFound Apr 13 '18 at 23:30
Use a a class constant: `LinkedList.class`. – Johannes Kuhn Apr 14 '18 at 00:24
