  • How to find the superclass name by using the getSuperclass() method

    In Java, class hierarchies follow the single inheritance model, i.e. a class can have at most one superclass. The only class that does not have any superclass isjava.lang.Object, while all other classes, including user-defined classes, derive (directly or indirectly) from Object. Thejava.lang.Class class provides a method, called getSuperclass(), to retrieve the direct superclass (i.e. the next class encountered when walking up the hierarchy) of a given class; this method returns a Class object representing the superclass of the Class object on which the method is called; if the method is called on the Object class,null is returned.
