String.split ( "." ) not working?

[mona]

Hi:

I'm usin GWT 1.1.10. When I tried to split a string on the dot symbol
using String.split ( "." ), I get an array of the length of the entire
string with nothing in each of the array element. I then tried
String.split ( "\.") but then the GWT compiler says "Invalid escape
sequence". I think this is a bug.

Basically, I would like to split a string like "a.b.c" and get "a",
"b", and "c" separately.

thanks,
Mona

No. Not a bug. You have to escape the escape character! :o)

 

backslash-dot is invalid because Java doesn't need to escape the dot.

 

You've got to escape the escape character to get it as far as the regex which is used to split the string. eg.

String[] x = ((String)"123.234.345").split("\\.");
Window.alert(x[1]);

 

will display "234"

Alternatively you can use split("[.]")

I tried the String.split ( "[.]" ) and that worked, thanks Ian!
