it is not so tough but it is not so easy to you will require 3 things first how to use string tokenizer and second a some no how of file streams and some info on java

no one is going to write code for you

this guy did write it: http://beginwithjava...ile-reader.html ,
and here's his code, which works perfectly well and was hugely helpful to me, especially to learn how to do it: I hope others find it helpful too!

// CSVRead.java
//Reads a Comma Separated Value file and prints its contents.
import java.io.*;
import java.util.Arrays;

public class CSVRead{

public static void main(String[] arg) throws Exception {

BufferedReader CSVFile =
new BufferedReader(new FileReader("Example.csv"));

String dataRow = CSVFile.readLine(); // Read first line.
// The while checks to see if the data is null. If
// it is, we've hit the end of the file. If not,
// process the data.

while (dataRow != null){
String[] dataArray = dataRow.split(",");
for (String item:dataArray) {
System.out.print(item + "\t");
}
System.out.println(); // Print the data line.
dataRow = CSVFile.readLine(); // Read next line of data.
}
// Close the file once all data has been read.
CSVFile.close();

// End the printout with a blank line.
System.out.println();

} //main()
} // CSVRead

StringTokenizer is legacy code
Use a Scanner to read the file line per line using scanner.nextLine()
use the String class split(",") method to split that line into an array of token

A word of warning: the following is a perfectly legimate 3-field csv line, which will break your code if you use String.split:

a,"foo,bar",b

Better to use a proper csv parser such as Ostermiller
