Write a java class called PTA0 in package labPT which has a single 
private field called "data" which is an Array of Strings.

Write a single creator for your PTA0 class which takes a single String 
parameter. A class called PTData has been provided for you that has a 
single static method called getData. Your creator should invoke the 
PTData.getData method, passing the parameter to the creator on as  the 
parameter to getData, as in: 

	data = PTData.getData(parm);
	
Write a method for your PTA0 class called "getFirst()" which returns 
the first word in data based on an alphabetic comparison. You can compare
two Strings, a and b, using the "a.compareTo(b)" String method. If "a" 
comes before "b", a negative integer is returned; if "a" equals "b", a
zero is returned, and if "a" comes after "b", a positive integer is 
returned. If data is empty, return a null string.

Write a method for your PTA0 class called "printData" which writes all 
the strings in data, one per line, to the terminal using System.out.println.

Write a "main" method for your PTA0 class that tests your creator, the 
getFirst method, and the printData method. Remember, a main method starts 
out as...

	public static void main(String[] args) {...
	
When creating a new PTA0 object, pass in the parameter "A0" to get some
test data.
