Question

I am trying to break string on delim “//”. My string also contains “/” and StringTokenizer giving strange result, it also break string on “/”.

  String  mStr = "abcd//aaa//32434//3/34343";
        StringTokenizer tok = new StringTokenizer(mStr, "//");
        while(tok.hasMoreTokens()){
            System.out.println(tok.nextToken());
        }

the result is

abcd
aaa
32434
3
34343

And the expected result is

    abcd
    aaa
    32434
    3/34343

Why this is happening and what is the solution of it? I do not want to replace “/” with other characters.

Answer 1

StringTokenizer takes both the tokens as separate, and tokenizes on both of them. So, it is tokenizing on both // and /, and hence the result.

I would rather prefer String#split over StringTokenizer. It’s easier to use, and has more options. It can take Regex as parameter, and returns an array of tokens which you can use later on: –

String  mStr = "abcd//aaa//32434//3/34343";

String[] arr = mStr.split("//");
System.out.println(Arrays.toString(arr));

Output : –

[abcd, aaa, 32434, 3/34343]
