Mockito method parameter matcher with generic in java

Question

My actual method signature is:

public List<T> readFileToMemory(FooFile fooFile, **Class<T> entityClass**) { }

and I am trying to mock this as:

when(mockObject.readFileToMemory(any(FooFile.class), Matchers.any(Class<Bar>)).thenReturn(new ArrayList<Bar>())

but second argument doesn't compile. How to fix it?

I referred to the following answers but still no luck.

Just a note for other people just finding this: Matchers is deprecated in favor of ArgumentMatchers now.

You could also get it working with:

when(mockObject.readFileToMemory(any(FooFile.class), eq(Bar.class))) .thenReturn(new ArrayList<Bar>());

No, this throws me error as "Wrong 2nd argument type, required: java.lang.Class<Bar>"
