Java implementation of Binary Heap (source code)

Binary Heaps are one of the easiest and most popular means to implement priority queues. You can get a lot of tutorials explaining the algorithms for insertion, deletion of the maximum (or minimum) element and using the heap for implementing priority queue.

Preparing your Spring Development Environment.

Install JDK EE 7. Install Eclipse IDE for Java EE Developers, Luna.

From Eclipse Marketplace, install Maven Integration for Eclipse (Luna and Newer) It should already be there so just update it.

From Eclipse Marketplace, install Spring IDE plugin.
