Method Detail

main

public static void main(java.lang.String[] args)

This method is responsible for the creation of the PointCP object. This can be done in two ways; the first, by using the command line and running the program using java PointCPTest <coordtype (c/p)> <X/RHO> <Y/THETA> and the second by getting the program to prompt the user. If the user does not enter a valid sequence at the command line, the program will prompte him or her.

Parameters:

args[0] - The coordinate type. P for polar and C for cartesian.

args[1] - The value of X or RHO.

args[2] - The value of Y or THETA.

getInput

private static PointCP getInput()
                         throws java.io.IOException

This method obtains input from the user and verifies that it is valid. When the input is valid, it returns a PointCP object.

Returns:

A PointCP constructed using information obtained from the user.

Throws:

java.io.IOException - If there is an error getting input from the user.
