If your method overrides one of its superclass's methods, you can invoke the overridden method through the use of the keyword super. You can also use super to refer to a hidden field (although hiding fields is discouraged). Consider this class, Superclass:
public class Superclass {
public void printMethod() {
System.out.println("Printed in Superclass.");
}
}
Here is a subclass, called Subclass, that overrides printMethod():
public class Subclass extends Superclass {
public void printMethod() { //overrides printMethod in Superclass
super.printMethod();
System.out.println("Printed in Subclass");
}
public static void main(String[] args) {
Subclass s = new Subclass();
s.printMethod();
}
}
Within Subclass, the simple name printMethod() refers to the one declared in Subclass, which overrides the one in Superclass. So, to refer to printMethod() inherited from Superclass, Subclass must use a qualified name, using super as shown. Compiling and executing Subclass prints the following:
Printed in Superclass.
Printed in Subclass
