I'm facing issues in my code. Please Help

Please look into the code and help me in resolving this.

package com.qtpselenium.hybrid.suitea;

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

import com.qtpselenium.hybrid.base.BaseTest;

public class loginTest extends BaseTest {

	@Test(dataProvider="getData")
	public void doLogin(String dummyData) {
		System.out.println("Running Login Test");
	}
	
	@DataProvider
	public Object[][] getData() {
		Object[][] data = new Object[2][1];
		data[0][0]="a";
		data[1][0]="B";
		return data;
	}
}

Let me know if this needs some improvement.
