Narrative:
On takeoff roll near V1 the captain and I both noticed an audible click and looked up at the overhead panel. A pitch trim switch had tripped with no other indications. Shortly after rotate we got a master caution that was associated with an ADC2 (air data computer) failure and the captain pointed out that the engine page was showing on the right ECAM and that we had no oil pressure in the #2 engine. I reverted my air data computer to #1 air data computer and that fixed that problem. The ECAM was then filled with multiple failures; none of which were associated with the low oil pressure.the analogue gauge confirmed that we had no oil pressure in the #2 engine and we were expecting an imminent failure of the #2 engine so we turned toward the airport and [advised ATC]. We received no other indications of or ECAM warnings of the engine failing so we decided to keep it running. The captain called for and I executed the engine out immediate return checklist and complied with ATC instructions. We were vectored due to another emergency return by a different aircraft. We landed uneventfully and taxied clear. After being inspected by the fire dept. We taxied to our spot and shut down normally.
