TESTNG-EXCEL - Unable to ignore the first line in excel

Hi,
I am trying to get data from excel sheet but unable to ignore the first line in which it is username and password
with my code below it prints
username-----password
harsha1-----password1
harsha2-----password2
harsha3-----password3
harsha4-----password4

BUT I DONT WANT username and password obviously in my code below if I CHANGE for(int x=1;x<noofrows;x++)
then I get

null-----null
harsha1-----password1
harsha2-----password2
harsha3-----password3
harsha4-----password4


what to do ?

my code
package Rough;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;

import org.apache.poi.ss.usermodel.Cell;
import org.apache.poi.ss.usermodel.Row;
import org.apache.poi.ss.usermodel.Sheet;
import org.apache.poi.ss.usermodel.Workbook;
import org.apache.poi.ss.usermodel.WorkbookFactory;
import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class NewExcel {
public static Row r ;

@Test(dataProvider="testdata")
public void print(String username, String pass)
{
System.out.print(username+"-----"+pass);
System.out.println();
}
//@DataProvider (name="testdata")
@DataProvider(name="testdata")
public Object[][] readdata() throws Throwable
{
InputStream Ip = new FileInputStream ("C:\\Workspace3\\Parks_Victoria\\src\\Data\\TestSuiteData.xlsx");
Workbook wb = WorkbookFactory.create(Ip);
Sheet s =wb.getSheet("TestData");
int noofrow = s.getLastRowNum();
int noofrows = noofrow+1;
System.out.println(noofrows);
r = s.getRow(0);
int columncount = r.getLastCellNum();
System.out.println(columncount);
String inputdata[][] = new String [noofrows][columncount];


for(int x=0;x<noofrows;x++)
{
r =s.getRow(x);
for(int y =0; y<columncount; y++)
{
Cell c = r.getCell(y);
inputdata[x][y]= c.getStringCellValue();
//System.out.print(c.getStringCellValue());
}
// System.out.println();
}
//Cell c = r.getCell(3);
//System.out.println(c.getStringCellValue());
//return null;
return inputdata;
}
}
