1) consider a mass less spring.the mass is pulled to one of its ends while it's other end is fixed to a rigid support.As the Spring is pulled, a restoring force comes into play.So work has to be done against this force.This work done gets stored in the system in the form of elastic potential energy
2)The complex spring of a dart gun also store elastic potential energy.
When the trigger is pulled, the spring applies a force on the dart to do work.

Elastic Potential Energy is the energy possesed by body by virtue of its change in its size and shape.
Example:
1. Stretching of rubber band possess elastic P.E. When released it converts into K.E and can do some work.
2. Winding of key in toy car where muscular energy is used to change the spring size.... Energy is stored in the spring. When released the toy car moves.
