Juxtaposition and oxymoron

I'm getting confused with the difference between juxtaposition and oxymoron
Please can somebody help me out here!
Thanks

Oxymoron relates to a sentence. For example: 'we were alone, together' or a 'there is a deafening silence'. I.e where contradictory terms appear together. Just think of 'yes, no' - even though it would be impossible for that to ever be correct in a sentence.

Juxtaposition is simply placing 2 things closely together so that they can be contrasted - though it doesn't relate to a sentence. It can be 2 images for example.

So they are not related, but i can see where the confusion lies.

Does that make sense?
