I attempted to use
the coordinates of 38?53'50"N 77?0'22"W for Union Station (DC) and
since the program does not prompt me for param input, I manually
edited
the source code for the map.put method to
read as
map.put( "38?53'50\"N", "77?0'22\"W" );
// thought one backslash character is to escape special character like
quote
The code runs just fine. The debug console prints the following:
Dec 27, 2006: {38?53'50"N=77?0'22"W}
However, that seems meaningless unless I did not use it correctly. I
was expecting some sort of map albeit simple.
You DO have a simple map. More specifically, you have a string
representation of a map which has a single point as it's domain
("38?53'50"N") and a single point as it's range ("77?0'22"W"). Perhaps
the
confusion arises because you were expecting some sort of geographical
map?
"Map" here is in the mathematical sense:

But this is oxymoronic. First of all, 38?53'50"N=77?0'22"W is
plainly wrong,
It is possible to design a Java program to print a lie to console. E.g.
public class Liar {
public static void main(String[] args) {
System.out.println("2 + 2 = 5");
}
}
38?53'50"N <> 77?0'22"W,
one of them is longtitude and the other is latitude and the print out
is meaningless as far as I'm concerned.
It is possible to design a Java program to print out meaningless output
to the console. E.g.
public class Liar {
public static void main(String[] args) {
System.out.println("l;kjf9fa3hodf");
}
}
But if you're saying using
them for further calculation or processing (in math term) then that
would make sense.
I'm suggesting that you may be assuming the program does more than what
it actually does.
It's kind of an interesting start for Lew to post
it, however, it needs a step further for any value.
I think the value of the program lies in it being an example that uses
the 3 packages you listed, exactly like you requested. Nobody claimed it
would produce meaningful output.
