Static methods between inheritance classes - Java. Why does bunched up aluminum foil become so extremely hard to compress? Otherwise, we can use them like we use by Hasa-relation. As per the rules of method overriding, method call is resolved at run time by the type of object.So, in our above example d.hello() in second example should call hello() method of DisplayMessage class because reference variable of Display class is referring an object of DisplayMessage but it call Display class hello() itself.This happens because static method is resolved at compile time.
