May 15, 2012 · Based on my recent Java studies . method overriding, when the subclass have the same method with the same signature in the subclass. Method hiding, when the subclass have the same method name, but different parameter. In this case, you're not overriding the parent method, but hiding it. Example from OCP Java 7 book, page 70-71:
Jul 23, 2012 · Method hiding has to be used when you want to have a flexibility to call super class method or child class method based on your need. Overriding is used when your super class method need not be executed. i.e, if you think that, your super class method is no more useful to you and your child class method fulfills all the requirements, then go ...
Nov 12, 2015 · 0. I think it's called "hiding" because you can no longer access the superclass's method simply by writing the method name. Without the public static void testClassMethod() definition in Cat, your main could say. testClassMethod(); to call the method defined in Animal. But you can no longer do that.
Aug 22, 2012 · In short, the benefit is that you can implement a static method in a subclass which has the same signature as a static method in a superclass. If you could not do this, you couldn't add such methods to sub classes, and if you added such a method to a superclass all its subclasses would fail to compile. BTW: You can make a static method not ...

Apr 28, 2018 · But the idea of hiding by class methods is different: If a class C declares or inherits a static method m, then m is said to hide any method m', where the signature of m is a subsignature (§8.4.2) of the signature of m', in the superclasses and superinterfaces of C that would otherwise be accessible (§6.6) to code in C.
Jul 1, 2013 · Java won't resolve method call at runtime and depending upon type of Object which is used to call static method, corresponding method will be called. It means if you use Parent class's type to call static method, original static will be called from patent class, on ther other hand if you use Child class's type to call static method, method from child class will be called.
Jul 30, 2012 · To overwrite a method means that whenever the method is called on an object of the derived class, the new implementation will be called. To hide a method means that an unqualified call to that name (like the hidden() call in the inherited() method of my above example) in the scope of this class (i.e. in the body of any of its methods, or when ...
