Java IO Problem

[hugo84]

Hi Guys I have a textfile in the following format, the integer value before the ":" delimeter states the column where the value after the ":" should be stored in a 2D array. For Eg: 21:1.00, this should go into the 21st column of the array with the value 1.00. Therefore if you print out array[0][21] or array[1][9] it should give you the value of 1.00. Column numbers not stated in the textfile have a value of 0 for eg: array[0][0] to array[0][20] all will have values initialised to 0. So for each line it will read its column and value and store it into the correct array[][] parameters. How do i go about doing it?? Any help is appreciated thank you

Example of TextFile
21:1.00 42:1.00 63:1.00 84:1.00 105:1.00
9:1.00 32:0.50 41:0.50 44:1.00
3:1.00 5:0.50 8:0.50 15:1.00
.........
....

Code so far:
public static void ReadFile2String(String InputFile) {
String line = " ";
int storeArray[][] = new int[1700][357];//1700 rows and 357 columns each row
try {
FileReader fr = new FileReader(InputFile);
BufferedReader br = new BufferedReader(fr);
while ((line = br.readLine()) != null) //loop through each line
{

StringTokenizer st = new StringTokenizer(line, ":");

while (st.hasMoreTokens()) {
String s = st.nextToken();
System.out.println(s);
}

}


} catch (Exception e) {
System.out.println(e);
}
}

You forgot to use [code] tags.

Avoid using StringTokenizer, it is not deprecated but its use is discouraged. Use the String.split() method instead.

In your case you will have to use it twice: first to split the line read from the file at the spaces between the column/value pairs, and then to split each of these at the :.
