Am trying to split the String as (^) Separeted. Even I tryed Split method also..Any Other Way to split this one.. Please assist Me


I seen the String Tokenizer class they were charAt method for searching. This may be a reason for my problem.

Regular Expression is the only Option

Look closely at what you are separating on; you are getting exactly what you have requested.
And please use String#split rather than StringTokenizer, as explained in the API.

I tryed and finally I got this.. For the above example the beloew code splits the string to (^) separeated..

String delimeter = "\\(\\^\\)";
temp = str.split(delimeter);
for(int i =0; i < temp.length ; i++)
System.out.println(temp[i]);

Sorry, I was confused about what you wanted to split on.
But using StringTokenizer, if you look through the constructor details, it appears to use any part of the delimiter to split. So it can split on ( or ) or ^ or (^ or ^) or (^).
You have found out (well done ) how to get the whole pattern into a regular expression.

how to get the whole pattern into a regular expression. ??? Am not getting this one..

This is my actual Code to split the strings to "(^)" separated
( - Special Character. So i need to add "/". And the slash is also a special character. so I need to add 1 more "/". And thats it.

String[] temp = str.split("\\(\\^\\)");
for(int i =0; i < temp.length ; i++)
System.out.println(temp[i]);

I'm not sure what your question is here? The pattern you have provided is correct.
