String Tokenizer - getting the 10 th Token

[rastas biggs]

Hi ther I have text file with values seperated by "|"

I want to get the 10th Value



How might I achive this my code below

  
 
String line = "1|2|3|4|5|6|7|8|9|10|11|12|13|14|15"
 
StringTokenizer st = new StringTokenizer(line, "|");
if(st.hasMoreTokens())
      {
String SIM = (st.nextToken());
if(SIM.length() == 20)
  {
    errorSIM.add(SIM);
  }
 }
  }

Why not keep a local count of the tokens parsed?

String line = "1|2|3|4|5|6|7|8|9|10|11|12|13|14|15";
StringTokenizer st = new StringTokenizer(line, "|");
String SIM="";
for(int i=0;(i<[B]9[/B]) && (st.hasMoreTokens());i++)
{
             st.nextToken();
}
System.out.println(st.nextToken());
 

the above code will give you the 10th token but my guess is you want it to be dynamic and not fixed to get the 10th token only.
just make sure the number in "i<___" has to be one less than the value which you need.
Let me know what happened.
You can change the value in the for loop to get the desired value.

Using String.split would be easier:

line.split("\\|")[9];

Note that | is a special character in a regular expression and therefore needs to be escaped.

Just to be ornery, be sure to test with missing elements, too:

String line = "1||3|4||6|7||9|10|11|12|13|14|15"

Seriously, this is a good exercise just for future reference even if your input will never be that messed up for this program. It can be solved with StringTokenizer, String.split or Scanner.

Stan,

will null values not be Tokenized?

Guys,

this is great feedback thanks for your help

Try em and see! If you think you'll run into that kind of input, look at the other constructor for StringTokenizer and try that one, too.
