It is an automatic procedure for which there are no efforts poured in to do so where a sub-class object is referred by a superclass reference variable.Casting from a subclass to a superclass is called upcasting. Typically, the upcasting is implicitly performed by the compiler. Upcasting is closely related to inheritance — another core concept in Java. It's common to use reference variables to refer to a more specific type. And every time we do this, implicit upcasting takes place.Type Casting In Java. 4. Operators.
