#6.4 Java Tutorial | Method Overriding | Super Keyword
Method Overriding:
what we have been discussed in this lecture?
a)method overriding
b)use of super keyword
What is method Overriding?
It is way to override the parent class method in child class .
class Parent{
int a;
public void show{System.out.println("this is parent");}
}
class Child extends Parents{
int a=10; //override a
public void show(){System.out.println("this is child method");} //method override by child class
public void useParentShow(){
super.show();
}
}
class Main{
public static void main(String []args){
Child c=new Child();
c.show(); //call the child class override method
c.useParentShow(); //get result of parents method
}
}
b) Now you are interested to use parents class show() then for that super keyword come into picture
whenever you want to use parents class method or variable in child class then we can use it by super keyword;
class Child extends Parents{
int a=10; //override a
public void show(){System.out.println("this is child method");} //method override by child class
public void useParentShow(){
super.show(); //help to use method of parents class
}
}
