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
}
}
}

Describe these concepts: Polymorphism, Inheritance and Abstraction.
Write a program to compute for numeric grades for a course. The course records are in a file that will serve as the input file. The input file is in exactly the following format: Each line contains a student's first name, then one space, then ten quiz scores all on one line. The quiz scores are in whole number and are separated by one space. Your program will take it input from this file and sends it output to a second file. The data in the output file will be exactly the same as the data in the input file except that there will be one additional number (of type double) at the end of each line. This number will be the average of the student's ten quiz scores. Use at least one function that has file streams as all or some of its arguments.
