Specification

Modify a Java application that prints the value of the mathematical constant Pi.

Copy the PiDay.java program and do the following:

• implement the abstract methods that are declared in abstract class Number;
• implement the two methods marked "TBI (To Be Implemented)" in PiDay.java;
• answer the three questions/exercises presented in the program's file comment block.

The output of your program must match the following:

byteValue(): 3 shortValue(): 3 intValue(): 3 longValue(): 4 floatValue(): 3.1415927 doubleValue(): 3.141592653589793
