In Java, besides the native types bool, int, long, etc., everything is an Object. When you define a Object variable, it points to the object, to null, or in certain cases can be uninitialised. Both point to a String object, one with no characters (length=0), the other to the foo three characters. The uninitialised case is a special one. When you're defining a class property, java auto-initializes the variables, but if they are variables inside your method, they aren't. class Foo { private String s; // defaults null private int i; // default zero }.
