How to parse a file ?

Question

I would like to know how could I get information from a file. This file contains picture names and vectors which characterize this picture. For each picture, there is a line with the the following syntax :
[filename] [1st Number of the Vector] [2nd Number of the Vector] [3rd Number of the Vector] ...
What is the best solution to get the all information ?
Thanks for your help

Hi,
are the [ ] part of the file?- Anyway, read in the file line by line and get the parts of it using a StringTokenizer. The following method will write them to a Vector:
public Vector getLineContents(String line) {
Vector v = new Vector(2,2);
StringTokenizer st = new StringTokenizer(line," []");// without [] if they are not part of the format
while (st.hasMoreTokens()) v.add(st.nextToken());
return v;
}// end of methodthis will give you a Vector, where each element is a string, that contains a part of that line. You did not say, which number format is used there, so I could not implement the correct parsing for it - but that is also done within 3 lines of code.
