Question

I am using StringTokenizer to tokenize a string with $$ as delimeter but if my string is like $1$dga74 then it tokenize this from first $. Can any body tell me why this happens and what can I do to remove this issue.

String str="/getCPage.asp?m=total&sub=$1$dga74$$/getEpage.asp?m=tatal&sub=0";
StringTokenizer tok=new StringTokenizer(str,"$$")
String url1=tok.nextToken();
String url2=tok.nextToken();

Answer 1

Each character in the delim argument is treated as a delimiter character. If you specify "$$" you specify $ twice (the second is ignored).

To solve your problem you can use a Scanner:

public static void main(String[] args) {

    String s = "/getCPage.asp?m=total&sub=$1$dga74$$/getEpage.asp?m=tatal&sub=0";

    Scanner scanner = new Scanner(s);
    scanner.useDelimiter("\\$\\$");

    System.out.println(scanner.next());
    System.out.println(scanner.next());
}

Outputs:

/getCPage.asp?m=total&sub=$1$dga74
/getEpage.asp?m=tatal&sub=0
