Minecraft Item Sorter with Overflow Handling

This is a basic item sorter you can use as soon as you begin getting iron. The advantage of this item sorter is the overflow handling. If a chest completely fills up, you can send the overflow to secondary storate, use the overflow for smelting, fuel, or bonemeal... or you can simply destroy it.
This video includes highly detailed explanations of how this sorter functions after showing the method of building it.
This is developed for Bedrock, but should work well in Java.
