How can I make this testNG test dynamic but remain parallel

public class FactoryTest {
    
    @Test  
    @Parameters("Row")
    public void run1(int row) throws MalformedURLException{           
        new Controller(row);
    }
    
}

                    </include>

This is an example of one of the tests I need to run. I need it to run in parallel with other tests. So in the test run1() I create a Controller(row) which initiates the test and I pass a row number to it. I want to run new Controller(1) and new Controller(2) and new Controller(3), etc all at the same time. I am able to do this if I change the java file to this:

public class OfficialTest {
    
    @Test    
    public void run1() throws MalformedURLException{           
        new Controller(1);
    }
    
    @Test    
    public void run2() throws MalformedURLException{           
        new Controller(2);
    }
    
    @Test    
    public void run3() throws MalformedURLException{           
        new Controller(3);
    }
    
    @Test    
    public void run4() throws MalformedURLException{           
        new Controller(4);
    }
    
    @AfterMethod
    public void close() {
        System.out.println("closing");
    }
}

but this isn't dynamic. I need to be able to run this using any range of number for the row. So I was thinking maybe I could generate an XML file that would take care of this but I still am not sure if it would even be able to run in parallel that way.

I was able to fix it with this:

public class ParallelTests 
{

	int row;
    
    @Parameters({"Row"})
    @BeforeMethod()
    public void setUp(int rowParam) throws MalformedURLException
    {           
       row = rowParam;
    }
    
    @Test
    public void RunTest() throws InterruptedException, MalformedURLException
    {
    	new Controller(row);
    }

}
