The easiest way to sort an array is using the Collections.sort methods. You have a choice of two methods. If your object has a natural order, you can consider to make it implement the Comparable interface (as Manuel suggested). In this case the list can be sorted according to this order...

Instance Methods: Instance methods are tied to an object, so you can only call them on an instance of a class Example: String.toLowerCase() is an instance method, so you need a String object to call it: String str = "HELLO"; String result = str.toLowerCase(); // Called on the ...
By contrast when sorting objects, including sorting objects by a key of primitive type, you’re sorting pointers. The objects themselves do have an independent nature separate from their key values. Sometimes this may not matter all that much—e.g. if you’re sortingjava.lang.Strings—but ...
