    Collections classes are heart of java API though I feel using them judiuously is an art.its my personal experience where I have improved performance by using ArrayList where legacy codes are unnecesarily used Vector etc.JDK 1.5 introduce some good concurrent collections which is highly efficient for high volume , low latency system.
