I suggest using Java CSV Library, it is very easy to use. If you use Maven 2, you can use this to load it as a dependancy.

<dependency>
  <groupId>net.sourceforge.javacsv</groupId>
  <artifactId>javacsv</artifactId>
  <version>2.0</version>
</dependency>

The code below reads in a CSV file, parsing one line at a time, splitting each line into the vals array.

CsvReader rdr = new CsvReader("simeFile.csv");
while (rdr.readRecord()) {
    String[] vals = rdr.getValues();
    ...
    System.out.println(vals.length);
    // process here
}
