Last Question: Checking if an item is [blank]

Quick question. I have my fueling function, but I wanted to have the turtle to check it's other inventory slots for coal before it shuts off if it's designated "fuel" slow runs out. I was thinking of using the "turtle.getItemDetail()" and then using a boolean to check if the slot has an item with the name "minecraft:coal". How would I go about checking if the returned name information matches "minecraft:coal"?

Last question, I promise :P/>

You may be better off using turtle.refuel(0). This doesn't actually refuel the turtle, but it still returns true if the currently selected slot contains a valid fuel unit, or false if it does not.
