(4) Assume, you will receive rent payments over a time period of
88 years. For the first 44 years, you will receive a rent of $444
at the end of each year. For the next 44 years thereafter you will
receive $222 at the beginning of each year.
Assuming a discount rate of 4% calculate the net present value of
this income stream. (a) Employing the equation for identical
payments over a limited time period, show how you would alter this
equation applied to this problem. Show the abstract formula.
(b) Now, calculate the NPV of the payments.

The abstract class SayHello and the static method process are defined as followed:
class SayHello
{
private String greeting;
SayHello( )
{
greeting = “Hello guys”;
}
SayHello( String wts )
{
greeting = wts;
}
void printGreeting( );
}
static void process( SayHello obj )
{
obj.printGreeting( );
}
Write the statements to instantiate an object (with its instance variable initialized with the string “Bonjour mes amis” ) of the anonymous class that extends this abstract class by using the following definition of printGreeting( ); then write a statement to call method process by passing to it that object.
void printGreeting( )
{
System.out.println( greeting );
}
