A red-black tree algorithm in java refers to a binary tree +1 bit per node, which is red or black in color. The leaves of the binary tree are empty (nil) and black in color. A single sentinel, nil(T) is used for all the leaves included in red-black tree T. Color[nil[T]] is black and the roots parent is nil[T] too. The red-black trees(key, left, right and p) acquire the characteristics of binary search trees. The key in nil[T] is not considered.

Red-black properties:

  • Each node is red or black.
  • The root is black.
  • Every leaf (nil[t]) is black.
  • A red node has both black children.(In between the root to a  leaf, two reds in a row can’t be found on the same path.)
  • All paths passing from the node to descendant leaves comprise of equal number of black nodes, for every node.

Hardware Requirement:

The system should have a  Pentium III  with 733 MHz  processor, a RAM of 256 MB, a Hard Disk of 10 GB, a Screen Resolution of 800 by 600 and a Color Quality of 16 bit.

Software Requirement:

The system should have all versions of Windows (Operating software) and frontend language software, JAVA.

Applications and related data structures:

Red-black trees provide worst-case guarantees for time involved in inserting, deleting and search. They are beneficial in time-sensitive applications like real-time applications as well as act as building blocks in many data structures that provide worst-case guarantees; for instance, several data structures that are used in computational geometry can rely upon red-black trees and they are also used by the Completely Fair Scheduler employed in current Linux kernels.
