I use split in Java like this

String str = "Bx=1946^Cx=1043423"; String[] parts = str.split("^"); for (String part : parts) System.out.println(part);

But it turns out there is only one element in parts array after splitting, so if I want to use "^" as delimiter, what should I write?

Thanks

    I'd highly recommend using the Apache StringUtils split methods over the standard java ones, especially seeing as they can use regular String delimiters without the potential added confusion of regex. Commented Mar 1, 2013 at 17:36

You need to escape the^, which has a special meaning in regex (start of word, line and others):

String str = "Bx=1946^Cx=1043423"; String[] parts = str.split("\\^"); for (String part : parts) System.out.println(part);

The output will be:

Bx=1946 Cx=1043423

Use

str.split(Pattern.quote("^"));

instead of

str.split("^");

Pattern.quote() works in case of splitting with multiple symbols too. For example, we can use str.split(Pattern.quote("^^^^")); instead of adding too many special characters like str.split("\\^\\^\\^\\^").

@TheThom why not? It does answer the question.
@MarounMaroun It does now. Thanks for the explanation.
