Method overriding is when a child class redefines the same method as a parent class, with the same parameters. For example, the standard Java class java.util.LinkedHashSet eâ¦xtends java.util.HashSet. The method add() is overridden in LinkedHashSet.
C++ and C# support overriding by explicitly using the keywords 'override' and 'virtual'. Java uses the 'super' keyword to invoke the superclass method. However, C++ does not have the super keyword and uses instead the base class name followed by the scope resolution operator (::).
