This post is part of a series on Java syntax and libraries for solving the problems in each chapter of uHunt, a tool for competitive programming practice. You can find the rest of the posts in the series by visiting my uHunt Java post category.

In the previous post in this series, a review of Java for uHunt Chapter 1 problems, I covered Java basics. This time around, I’ll be discussing the additional Java features required to solve the Chapter 2 problems. The problems in this chaper focus on data structures, so we’ll be looking at data structures supported by the Java Class Library.

As before, I have put full examples of all of these topics in my Reference.java reference class. You can look there to find sample code to try out.

Although I have covered Java language features in those and other posts, I thought it would be useful to provide an overall summary of the parts of Java that I found useful when solving the problems in that chapter.
