Java.lang.NoSuchMethodError: main

Question

I am still trying to read a csv file, but getting an error, see subject.
I think I nust go on a course as I just can't believe that it's thar hard just to read a simple csv file in java.
Can anybody recommend a good course that will explain all.
This is my source code, personaly I think it's in a mess....
package CsvReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
public class CsvReader {
     public CsvReader(FileReader fileReader) {
          // TODO Auto-generated constructor stub
     public static void main(String[] args,
          CsvReader CsvReaderthrows) throws FileNotFoundException
          CsvReader reader = new CsvReader(new FileReader("cash 20 feb 2009.csv"));
     String [] nextLine;
     while ((nextLine = reader.readNext()) != null) {
     // nextLine[] is an array of values from the line
     System.out.println(nextLine[0] + nextLine[1] );
     private String[] readNext() {
          // TODO Auto-generated method stub
          return null;
Help will bbe appreciated.
