WebHeap implementation in Java. In Java, Heap is a special type of data structure where the root node or parent node is compared with its left and right children and arranged according to the order. Suppose, x is a root node and y is the child node, property key (x)<= key (y) will generate min-heap, and that relation is referred to as "Heap Property".
