Sorting and Searching Algorithms and Project Euler

I've some extra time recently (well, not really), so I've decided to increase my understanding of sorting and searching algorithms.

The project hosting site above is where I'll be doing my work.

I'm also using this to get familiar with Java, and in particular: polymorphism, interfaces, exceptions, encapsulation, inheritance, and modularization.

I've also started doing some problems from the Project Euler site, an algorithm problem website. Here's some of my solutions:
