Data structures and algorithms in Java

   I followed Coursera and the Karatsuba Multiplication algorithm made me reignite my interest in algorithms and data structures. Coursera is a good start followed by the Data Structures and Algorithms in Java book. Learning logarithmic analysis is a prerequisite in my opinion.

   The two books that helped me the most were:

   Algorithms, 4th Edition by Robert Sedgewick. Material: http://algs4.cs.princeton.edu/home/

   and Data Structures and Algorithms in Java, 2nd Edition by Robert Lafore

   Both are in java.

   Data Structures and Algorithms in Java by Adam Drozdek has a lot of actual code that works. I think the code is online, but the book is worth buying because things are explained well (http://www.amazon.com/Data-Structures-Algorithms-Java-Drozde... ) to be fair, there's quite a bit of math supporting Drozdek's book. Stay away from Sedwick, in my experience his examples are incomplete/don't compile and are abstract. Now, while, CLRSS is the gold standard (Joshua Bloch cites it in his Java Collections code) be aware it's math heavy and lacking on implementation details. Rumor was that there was a CD of CLRSS examples somewhere...

   I graduated recently and we were taught C first and then C++ of OO concepts. I don't think anybody had issues learning OO concepts this way though most of what we learnt went out of the window when we started learning Data Structures and Algorithms in Java. It seemed a lot easier and a lot more could get done in the same amount of time spent on C/C++.

   But I still had a fascination with C. I tried to do a few networking projects using C which turned out to be more tiring than expected thus abandoning the whole project. I think if we would have stuck with C/C++ all the way through the Algorithm's class it would have been much more helpful. Java/Python is way too easy to pickup later on your own and reproduce the same results that one would in C/C++.

   I suggest that you work patiently through a good text on algorithms and data structures that has code samples in it. I recommend "Algorithms I and II" by Sedgewick or "Data Structures and Algorithm Analysis in Java" (or the C++ version) by Weiss. I also hear good things about "Data Structures and Algorithms in Java" by Lafore.

   The above books are quite apt for beginners. You should expect to struggle a little but you must persevere anyway. I remember struggling with sorting and matrix multiplication algorithms when I learned it the first time in school. Do not mistake your unfamiliarity with the subject for its inherent difficulty! Once you write a few sample programs and see how the algorithms play out, you'll get the hang of it.
