How do access specific tokens with Java's StringTokenizer?

Question

I'm using Buffered Reader to pass individual lines of a file to Java's StringTokenizer. The file is structurd as follows:

"2,0";"12345";"foo";"foo.doc"
"2,4";"23456";"foo";"foo.doc";"34567";"foo7";"foo7.doc";"45678";"foo6";"foo6.doc";"56789";"foo5";"foo5.doc";"67890";"foo4";"foo4.doc"   
"3,0";"34567";"foo7";"foo7.doc"
"3,0";"45678";"foo6";"foo6.doc"
"3,0";"56789";"foo5";"foo5.doc"
"3,0";"67890";"foo4";"foo4.doc"

Here's the code I'm using--so far.

public class parse {
  public static void main(String args[]) {
    FileInputStream inputStream = new FileInputStream("whidata0.txt");
    BufferedReader br = new BufferedReader(new InputStreamReader(inputStream)); 
    while((scrubbedInput=br.readLine())!=null) {
      StringTokenizer strTok = new StringTokenizer(scrubbedInput, ";", false);
      int tokens = strTok.countTokens();
      while (strTok.hasMoreTokens()) {
        tok01 = strTok.nextToken();
      }
      System.out.println("  scrubbed: " + scrubbedInput);
      System.out.println("    tokens: " + tokens);
      System.out.println("     tok01: " + tok01);
    }
  }
}

I need to be able to assign each token in a string to a variable to do additional manipulation. However, if I assign those variable in my while loop, the iteration will overwrite my variables, and they will all return with the same value.

I'm trying to devide a way to do the following:

String token01 = strTok.tokenNumber(0);
String token02 = strTok.tokenNumber(1);
String token03 = strTok.tokenNumber(2);
String token04 = strTok.tokenNumber(3);
etc.

but cannot find any methods in the String Tokenizer documentation that will allow that. I can certainly write each line to a String array of thisLineOfTokens[] and use a for loop to create String tokenN = thisLineOfTokens[n], but is there a more direct way to access specific tokens?

I'm kinda lost about the best way to reference a SPECIFIC token from my string.

Answer 1

You can use String.split for that instead of a StringTokenizer.

String[] split = scrubbedInput.split(";");

split[2]; //index=2

Answer 2

Info from here:

It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead.

So, you can use something like this:

String testLine = "your;test;data;"

String[] result = testLine.split(";");
for (int x=0; x<result.length; x++){
    System.out.println(result[x]);
}

Output:

your
test
data
