Can I instantiate objects from an array 1 at a time?

Question

I have a scripted object that instantiates objects from an array when it collides with something. That part working with this:

 GameObject[] biasBar;
 public int barNumber;

private void OnTriggerEnter2D(Collider2D other) { if(other.tag == "Object1") { Instantiate(bar[barNumber++], new Vector3(6, -4, 0), Quaternion.identity); } if(other.tag == "Object2") { Instantiate(bar[barNumber--], new Vector3(6, -4, 0), Quaternion.identity); } }

The problem is that I only want to have one object from the array on the screen at a time. Is there a way can I delete the current array object once the new array object is instantiated?

     GameObject[] biasBar;
     public int barIndex;
     private GameObject instance;
     private void OnTriggerEnter2D(Collider2D other)
     {
         if (other.CompareTag("Object1"))
         {
             if (instance != null) Destroy(instance);
             barIndex = Mathf.Min(barIndex + 1, biasBar.Length);
             instance = Instantiate(biasBar[barIndex], new Vector3(6, -4, 0), Quaternion.identity);
         }
         if (other.CompareTag("Object2"))
         {
             if (instance != null) Destroy(instance);
             barIndex = Mathf.Max(barIndex - 1, 0);
             instance = Instantiate(biasBar[barIndex],new Vector3(6, -4, 0), Quaternion.identity);
         }
     }
