Just started learning TestNG ,Getting an error trying to run a simple testNG example

package testcases;

import org.testng.annotations.*;

public class SearchAndBuyPhone {

@Test 
public void search() {
System.out.println("Searching for a Phone");

}

}

when run as testNG.test I get this error below ,wondering what is not right here 

The TestNG library is added 

Error occurred during initialization of boot layer
