How to Split a string using String.split()? Understanding the Java Split String Method. Let’s get started.
Java StringTokenizer:
In Java, the string tokenizer class allows an application to break a string into tokens. The tokenization method is much simpler than the one used by the StreamTokenizer class. The StringTokenizermethods do not distinguish among identifiers, numbers, and quoted strings, nor do they recognize and skip comments.
Java String Split:
Splits this string around matches of the given regular expression.
This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.
If you want to split by new line then you could use below:
|
1 |
String lines[] = String.split("\\r?\\n"); |
There’s only two newlines (UNIX and Windows) that you need to worry about.

If I have pass the multiple url from one activity to another activty,how to split and load the url?
Hi Arvind – you may need to atleast pass some delimiter in between URLs.
how to get only “Rs 100” in my list view from message “Rs 100 debited from xyz bank” string.
?
Hi Deepak – I hope this helps:
package crunchify.com.tutorials; /** * @author Crunchify.com * */ public class CrunchifyStringTokenizerAndSplit { public static void main(String[] args) { String delims = " "; String splitString = "Rs 100 debited from xyz bank"; String[] tokens = splitString.split(delims); for (int j = 0; j < 2; j++) { System.out.println(" " + tokens[j]); } } }how do i use combination of characters as a delimiter? I want to use “^S^” as the delimiter.
how i can created tokenization input code java .?please help me theworld_hendri@yahoo.co.id
Hey what font is that? in the first example where you declare class CrunchifyStringTokennizerAndSplit? Seems like the font is used by eclipse.
That’s right Rohit.. It’s eclipse’s default font.
Hi App Shah, I think it is not the default. I really liked that font, but my eclipse default font is very different from what is yours. Can you please share the name of the font from eclipse preferences? My eclipse default font is Consolas – Regular – 10
It’s Monaco – Regular – 11. I believe it’s default on Macbook then 🙂
thanks 🙂
