parsing a string an basis of a delimetre

[Nrapendra Sharma]

hi all,
I m trying to parse a string
";;67, Punjabi des Cinquante Otages;Nantes;;44000;France"
with ";" as delimeter
I have used StringTokenizer for this purpose

for (StringTokenizer t = new StringTokenizer(aValue, ";");
t.hasMoreTokens() {
String token = t.nextToken();
System.out.println(token);
}

i m getting four token instaed of 6
StringTokenizer is ignoring the initial two tokens...
can anyone tell me where i m doing wrong ??

Hi,
You will always get 4 tokens here.
StringTokenizer is used to parse a formatted text into set of discrete tokens based on the delimiters you have provided.
If your code is:

StringTokenizer strtoken = new StringTokenizer(str,";") 

you will always get 4 tokens all separated by delimiter.

But if you use :

StringTokenizer strtoken = new StringTokenizer(str,";",true)

in your code. Your no of tokens will be 4+6=10.. Becuase here when you specify "true" in the StringTokenized constructor, the no. of tokens will add the delimiter also as a part of discrete sets.
Hope this clarifies your doubt

You can try String#split(String regex) ..

Hello Nicky,

Welcome to JavaRanch.

Using split() method of String class is better option over StringTokenizer.
API documentation says:

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.
