Java class to retrieve data from the CSV file and create data provider out of it😉

 package csv;  
 import java.io.DataInputStream;  
 import java.io.FileInputStream;  
 import org.testng.annotations.DataProvider;  
 import org.testng.annotations.Test;  
 public class CsvFiles {  
      private static String line;  
      static int row;  
      static int cols;  
      static String[][] customers;  
      /*  
       * Retrieve data from the CSV file and return it has String two dimensional  
       * String array  
       */  
      private static String[][] getdata() throws Exception {  
           String filePath = "C:\\Users\\Mitturaj.h\\Desktop\\customers.csv";  
           DataInputStream dataInputStream = new DataInputStream(new FileInputStream(filePath));  
           /*  
            * initialized the array and give size of the columns and rows for CSV  
            * file data  
            */  
           customers = new String[2][3];  
           /* ReadLine() method is deprecated now, will need to find alternative  
            for this one ;)*/  
           while ((line = dataInputStream.readLine()) != null) {  
                String[] data = line.split(",");  
                // can find number of columns after splitting by comma  
                int cols = data.length;  
                for (int x = 0; x < cols; x++) {  
                     customers[row][x] = data[x];  
                }  
                // can find rows numbers by iterating the row variable ;)  
                row++;  
           }  
           return customers;  
      }  
      @DataProvider(name = "data")  
      public static Object[][] getdataprovider() throws Exception {  
           return getdata();  
      }  
      @Test(dataProvider = "data")  
      public void show(String fname, String lname, String city) {  
           System.out.println(fname + " " + lname + " " + city);  
      }  
 }
