Trying to split string on occurrence of double $$ charter in java

Question

I need to split my string with any occurrence of $$ for this string:

String tmpHash = "NA$notValid-1$notValid-2##notValid-3##$$VALID-1##$$VALID-2##$notvalid-4$$VALID-3";

Here is my code:

String[] arr=tmpHash.split("$$");

        for (int i = 0; i < arr.length; i++) {
            System.out.println("OUTPUT--> "+arr[i]);    

        }

OUTPUT IS

OUTPUT--> NA$notValid-1$notValid-2##notValid-3##$$VALID-1##$$VALID-2##$notvalid-4$$VALID-3

DESIRED OUTPUT

OUTPUT-->NA$notValid-1$notValid-2##notValid-3##
OUTPUT-->VALID-1##
OUTPUT-->VALID-2##$notvalid-4
OUTPUT-->VALID-3

You would have to escape the $ sign.

String[] arr=tmpHash.split("\\$\\$");

String myString = "$$";
String escapedString = java.util.regex.Pattern.quote(myString)

@ravz So it seems strange you didn't accept this answer then... – Duncan Jones Jun 18 '14 at 13:37
@AntonH Although your final paragraph looks rather similar to the end of [this answer](http://stackoverflow.com/a/3853764/474189). If you "borrowed" it, you should probably give credit where it's due. – Duncan Jones Jun 18 '14 at 13:40
@Duncan I didn't know how to reference an answer, and then got distracted . My apologies. Edited to reference answer. – AntonH Jun 18 '14 at 13:54

Best and short answer for splitting string having $$ is here we will be escaping $ because it is used in regex internally.

String[] arr=tmpHash.split("\\$\\$");
