Course Number:



Course Duration:
3 Days


Solid Java programming skills are required. At least 6 months of hands on experience with Java or graduating a Java boot camp are required.

Course Objectives:
  • Be able to explain the guiding principles behind analyzing an algorithm
  • Implement code and discuss the intent of the Merge Sort algorithm
  • Gain a deeper appreciation of the Java Collection Framework
  • Work hands on with less common collection classes
  • Understand and demonstrate Big O notation
  • See the benefits and speed of good hashing algorithms
  • Implement code and explain the motivation for using a Quicksort
  • Practice fundamental graph concepts
  • Learn to implement a Breath First Search
  • Implement code and analyze Dijkstra’s Algorithm
