intern() causes the String to go into the String pool.

This would be important if the String had been created using the new operator and therefore was out on the heap - not a good place to be if you want to optimize by re-using the same object in multiple places.
For efficiency you might force that object into the pool using intern(). Now it is available to be referenced for any other STrings that have the same value.
 
Don't get me started about those stupid light bulbs.
