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.
