join 2 objects

I made two shapes and now I need to join them together so they are one.
how?
thanks all

select them both (right click one, then shift-right-click the other)
and then ctrl J

The object you select last the ‘active object’, is the one that will keep it’s modifiers, so the first object selected will have any modifiers deleted and replaced with the active object’s (it’s all one object afterwards)

Thanks very much for such a good reply.
