Split a price String Object into dollars and cents String Objects

Hello All,

I am trying to split a String object below -:

String price = "150.0"
            String priceArr[] = price.split(".", 2);
            String dollars = priceArr[0];
            String cents = priceArr[1];

Why is it that 'dollars' is assigned "" and 'cents' is assigned
"50.0"? I would like 'dollars' to be assigned "150" and 'cents' to be
assigned "0". What am I doing wrong here? I appreciate any effort to
help me. Thank you for your time and consideration.

Sincerely,

Sisilla

Here is the solution if anyone is curious:

The period/dot is a special character in Regular Expressions and has
the meaning "any character". If you want to split around the dot, you
need to use the expression "/."

Oops. That should be "\."

Actually you need "\\."

By escaping the dot a reference to the dot is created, as opposed to
the 'any character' meaning; the backslask then needs to be repeated
because Java will strip a backslash before passing the expression to
the Regex engine.

you mean literal ., . is a magic regex command meaning any char.

You must "quote" it. See http://mindprod.com/jgloss/regex.html
