Java Generics for Loop Java 5 also got a new for-loop (also referred to as "for-each") which works well with generified collections. Here is an example: List<String> strings = new ArrayList<String>(); //... add String instances to the strings list... for(String aString : strings...

making it great for beginners. However, it does have a potential pitfall: it creates an empty ArrayList. If you need an ArrayList with predefined elements, you’ll need to add them manually using theaddmethod or use a different method of initialization, which we’ll cover in the next section...

From 8u20 release onwards Collection.sort defers to List.sort. This means, for example, existing code that calls Collection.sort with an instance of ArrayList will now use the optimal sort implemented by ArrayList.See 8032636.Area: core-libs/java.net...
When considering the behavior of generics in the Java platform, a very similar question can be asked: “Is List<String> a subtype of List<Object>?” That is, can we write this: // Is this legal? List<Object> objects = new ArrayList<String>(); At first glance, this seems entirely re...
