For example, Ive got Some stringa.b.c.d`, I have separated it by tokens. but now I want to do a specific thing with a, then something else with b, and something else with c. How can I do that?
String value="a.b.c.d"; StringTokenizer tokenize = new StringTokenizer(value, "."); while(tokenize.hasMoreTokens()){ String separated1= tokenize.?????; String separated2= tokenize.?????; String Val1 = someMethod1(separated1); String Val2 = someMethod2(separated2); } //tokenize next line is not solution Just to spell out what @RealSkeptic already said, avoid the loop:
String value = "a.b.c.d"; String[] separated = value.split("\\."); if (separated.length >= 2) { String val1 = someMethod1(separated[0]); String val2 = someMethod2(separated[1]); } else { // other processing here } You could do something similar with a StringTokenizer if you liked, only you would need at least two if statements to check whether there were enough tokens. But as @user3437460 said, StringTokenizer is now legacy; String.split() is recommended in new code.
Using String.split you can split about the . into an array.
How about something like this which will print each token:
String value = "a.b.c.d"; String[] tokens = value.split("\\."); for (String token : tokens) { System.out.println(token); } The . needs to be escaped as the split function takes a regexp and . is a wildcard
Why don't use split ? Easier to use and makes more sense here
ifstatements one after the other to check if there is still a token and get the next token and do something with it.
