Generics are a facility of generic programming that was added to Java in J2SE 5.0. I'm new to java and I got a test today and kind of failed to make it, I was hoping that someone could explain it to me because I still don't get how to use Generic collections. Generics is one of those more complicated language features in Java that is not well understood by many programmers. Since I've been taken to task in the past for my cogent observations of Java's, um, shall we say "unintuitive" behavior, particularly in the era of generics and autoboxing, I'm just going to put this one out there without making any (public (explicit)) value That is, inside the method, any subclass or SuperType could be added to the list (since it's just a Collection of SuperType) but then List would not only contain SubtypeOfSuperType objects. I just finished reading the Java Generics book by Maurice Naftalin and Philip Wadler. The book in question is - Java Generics and Collections, by Maurice Naftalin and Philip Wadler from O'Reilly Media. Perhaps everyone already knows about this, but I just found a very interesting feature of Java Generics - you can declare synthetic composite types using multiple bounds to allow you to treat two different classes that implement the same interfaces as if they had a common super Collection things = new ArrayList); // DOES NOT COMPILE this.add(new Foo()); this.add(new Bar()); doSomethingElse(things);. Generics in Java is one of those features where almost everyone uses but very people, including myself, really understand. Head First Java 16 Data Structures: collections and generics Page 529 to 579. Here are some most simple and common use of generics with collection. This is one of the first books on the Java Generics and Collections libraries. This one is basically a write-up of a collection of links about Java generics. Many avoid it interface Collection { public boolean addAll(Collection
