Answer
Deadlock occurs when multiple threads wait for each other's resources and none of them can continue.
Quick Answer
Deadlock is when two or more threads each hold a resource the other needs — so they all wait forever. Thread A holds Lock 1 and needs Lock 2; Thread B holds Lock 2 and needs Lock 1. Prevent by always acquiring locks in the same order, or using timeouts.
