First one is too small and blurred to tell, but looks like a choke?, the second is (fairly obviously) a very low inductance 'choke', just as used at VHF freqnecies.
I wouldn't say completely opposite - they both store energy.
Their I-V phase relationships are opposite perhaps.
Also, at sufficiently high frequencies, they sometimes swap roles (impedance-wise) due to inevitable parasitic elements in their contruction.
But, this is probably confusing to the OP so he should research the basic differences between a capacitor and an inductor.

Yes up to moderately low frequencies. Put a choke on a network analyzer if you've never done this... past 100MHz or so.. guess what, its a capacitor.. because the inter-winding capacitance starts to short the thing out... likewise, a capacitor starts looking inductive at a sufficiently high frequency due to the series inductance of the leads.. TRY IT!
