Cannot find symbol -method itemsSold (int)

this segment is causing an error which says cannot find symbol – method itemsSold (int)

 int total = itemsSold(0);
 int max = itemsSold(0);
 int min = itemsSold(0);

I am assuming it is with those lines

public class Payroll
{
    private int[] itemsSold;
    
    public Payroll(int[] i)
    {
        itemsSold = i;
    }
    
    public static void ingWords (String [] w)
    {
    for(String str: w)
      {  
     if(str.substring(str.length()-3).equals("ing"))
          {
              System.out.println(str);
     }
    }
   }
   public double computeBonusThreshold()
   {
       int total = itemsSold(0);
       int max = itemsSold(0);
       int min = itemsSold(0);
       
       for(int i= 1; i < itemsSold.length; i++)
       {
           total += itemsSold[i];
           if(itemsSold[i] > max)
           {
               max = itemsSold[i];
            }
            if(itemsSold[i] < min)
            {
                min = itemsSold[i];
            }
        }
        return (double)(total-max-min)/(itemsSold.length-2);
}
}

and the tester class incase it is causing the problem somehow

public class TestPayroll
{
    public static void main(String [] args)
    {
        String[] words = new String[] {"rolling", "hello", "watching", "goodbye", "hiking"};
        int[] sold = new int[] {48,50,37,62,38,70,55,37,64,60};
        
        
        Payroll.ingWords(words);
        
        Payroll company = new Payroll (sold);
        double threshold = company.computeBonusThreshold();
        System.out.println(threshold);
    }
    }

>Solution :

When you have parenthesis after itemsSold java thinks you are trying to call a method called itemsSold.

However your itemsSold is an array. To access array elements you need to use square brackets.

int total = itemsSold[0];
