Java generics are a very powerful and useful addition to the language. Although some of the details we delved into later in this chapter may seem daunting, the common usage is very simple and compelling: generics make collections better. As you begin to write more code using generics you will find that your code becomes more readable and more understandable. Generics make explicit what previously had to be inferred from usage. They complete the promise of type safety in the Java language and make Java a better language, despite their idiosyncrasies.
