You may also use the super keyword in the sub class when you want to invoke a method from the parent class when you have overridden it in the subclass.
Example:
public class CellPhone {
public void print() {
System.out.println("I'm a cellphone");
}
}
public class TouchPhone extends CellPhone {
@Override
public void print() {
super.print();
System.out.println("I'm a touch screen cellphone");
}
public static void main (strings[] args) {
TouchPhone p = new TouchPhone();
p.print();
}
}
Here, the line super.print() invokes the print() method of the superclass CellPhone. The output will be:
I'm a cellphone
I'm a touch screen cellphone
