His goal is give students an excellent background in creating data structures themselves, as well as make them comfortable using the standard library. Using the Java Collections Framework gives students the opportunity to work with excellent fully tested code. Further, since this is a standard library of classes, students will be able to continue to use it for other courses and as they move into industry.
