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.
You can use String.split
for that instead of a StringTokenizer
.
String[] split = scrubbedInput.split(";");
split[2]; //index=2
