Hello,
I am having problems using the method java.util.String.split(String) which
is supposed to split up
a string into an array of strings while cutting out a delimiter. For some
reason, when I use it, it
gives me an error. Could someone advise me as to how I should approach
this problem? I am
using the 2.12 build of Eclipse and the OS is Apple's Mac OS X 10.2.8.
Thank you.
Sincerely,
Paul Gribeluyk

Do you get an exception? What is it?
Split does work how you mentioned, so take the sentence:
"I like dogs" and do this:
String[] array = "I like dogs".split(" ");
this will return me:
array[0] = "I";
array[1] = "like";
array[2] = "dogs";
Is this how you are using it? Split TAKES a regular expression, so its
handy that most of the time simple characters will work, but if you pass
in soemthing like "?" which is a reserved character for regular
expressions, then you need to escape it "\\?" if you actually wanted to
split on question marks.
Best,

So here is how I use split:
BufferedReader buffread1 = new BufferedReader (new FileReader ( in1));
String exp = buffread1.readLine();
String [] expvalues = exp.split(",");
The file in1 contains double values, two per line, separated by commas.
The error message that I
get is this:
"the method split(String) is undefined for the type String"
Thank you for the help.

It would appear that you are compiling against 1.3 libraries.
String.split(String) was added in 1.4

1.4 libraries, but I'm not
sure how to let eclipse know that. Any ideas?

You need to configure Eclipse to use this as your JRE. Look under
