Java supports two types of polymorphism
1)compile time
2)Run time
1)Compile:---overloading is the best example of compile-
time polymorphism.
Look at this example:----
class NewClass {
public void aSum()
{
System.out.println("hi.......");
}
// NewClass nc1=new InheritClass();
// NewClass nc=new NewClass();
}
class InheritClass extends NewClass
{
@Override
public void aSum()
{
System.out.println("over-riden......");
}
public static void main(String as[])
{
NewClass nc=new NewClass();
NewClass nc1=new InheritClass();
nc.aSum();.......compile time polymorphism
reference type determine which method to be invoke
//nc1.aSum();
}
2)Run time:Over-ridding is the example of run time
polymorphism........
look at example----
class NewClass {
public void aSum()
{
System.out.println("hi.......");
}
// NewClass nc1=new InheritClass();
// NewClass nc=new NewClass();
}
class InheritClass extends NewClass
{
@Override
public void aSum()
{
System.out.println("over-riden......");
}
public static void main(String as[])
{
NewClass nc=new NewClass();
NewClass nc1=new InheritClass();
// nc.aSum();
nc1.aSum(); //object type determine which method
shuold call
//run the example u will get idea about that
}
}
}
