split method in string

[Saathvik Reddy]

Hi,

I have a simple string and want to split the string based on a regex. I am using split method to split the string
For Example:

 
 
String str = "sampleFile.csv";
String[] array = str.split(".");

Here the array size is zero.

If i replace with str="fname,lname"; and use str.split(",");

It works fine. Is there anything wrong with the period.

Thanks,
Srikanth.

A period has special meaning in a regex. It means to match anything. So, if you want to match an actual period, you will need to escape it... use "\\." instead.

Except new line characters (by default).
