Unable to parameterize test using @DataProvider

I created a new TestNg class YahooRegistration and wrote the following code using DataProvider :

package Test2;

import org.testng.annotations.DataProvider;
import org.testng.annotations.Test;

public class YahooRegistration {
@Test(dataProvider="testData")
public void RegisterTest(String username, String password, String email, String city){

System.out.println(username + "--" + password + "--" + email + "--" + city);
}

@DataProvider
public Object[][] testData(){
Object[][] data=new Object[3][4];

data[0][0]="user1";
data[0][1]="pass1";
data[0][2]="email1";
data[0][3]="city1";

data[1][0]="user2";
data[1][1]="pass2";
data[1][2]="email2";
data[1][3]="city2";

data[2][0]="user3";
data[2][1]="pass3";
data[2][2]="email3";
data[2][3]="city3";

return data;
}

}

But after running the code, getting the following exception on console :
