Try This 13-1 Create a Generic Queue

One of the most powerful advantages that generics bring to programming is the ability to construct reliable, reusable code. As mentioned at the start of this chapter, many algorithms are the same no matter what type of data they are used on. For example, a queue works the same way whether that queue is for integers, strings, or File objects. Instead of creating a separate queue class for each type of object, you can craft a single, generic solution that can be used with any type of object. Thus, the development cycle of design, code, test, and debug occurs only once when you create a generic solution—not repeatedly, ...
