stringtokenizer - trying to print out the array in java - 


system.out.println("please input elements , seperate each  comma."); e = dk.nextline(); string[] elems = new string[e.length()]; st = new stringtokenizer(e,",");  (int = 0; i<e.length(); i++) {    elems[i] = st.nexttoken().tostring(); }  (int i=0; i<e.length(); i++){    system.out.println(elems[i]); }

i trying print out array elems[] wont work error java.util.nosuchelementexception @ java.util.stringtokenizer.nexttoken(stringtokenizer.java:349 seems @ line:

elems[i] = st.nexttoken().tostring();

can me identify , understand problem?

a correct version:

string[] elems = e.split(","); for(string elem : elems) {     system.out.println(elem); }

the mistake made e.length() returns size of string (its number of characters) ended calling st.nexttoken() more times there actual tokens separated ",". hence exception.
