When one block in slot, it is not used

Hey, I got this:

 

public boolean enchantItem(EntityPlayer player, int i) {
	ItemStack stack0=tileEntityGrinder.getStackInSlot(0);
	ItemStack stack1=new ItemStack(ElectronicaEngineered.siliconGrindingItem,2);
	if(stack0.getItem()!=null)
	{


					tileEntityGrinder.getStackInSlot(0).stackSize--;
					if(tileEntityGrinder.getStackInSlot(1)==null)
					{
						tileEntityGrinder.setInventorySlotContents(1,stack1);
					}
					else
					{
						tileEntityGrinder.getStackInSlot(1).stackSize+=2;
					}




		}





	return super.enchantItem(player,i);
}

 

Runs fine, but when I put a single block in slot 0 or a single is left in there, it is not getting removed. How to fix

tried this:

public boolean enchantItem(EntityPlayer player, int i) {
	ItemStack stack0=tileEntityGrinder.getStackInSlot(0);
	ItemStack stack1=new ItemStack(ElectronicaEngineered.siliconGrindingItem,2);
	if(stack0.stackSize>=0)
	{


					tileEntityGrinder.getStackInSlot(0).stackSize--;
					if(tileEntityGrinder.getStackInSlot(1)==null)
					{
						tileEntityGrinder.setInventorySlotContents(1,stack1);
					}
					else
					{

						tileEntityGrinder.getStackInSlot(1).stackSize+=2;
						System.out.println(tileEntityGrinder.getStackInSlot(1).stackSize);
						System.out.println(stack0.stackSize);
					}




		}





	return super.enchantItem(player,i);
}

jeez, can someone just make it work for me?

ItemStack stack0=tileEntityGrinder.getStackInSlot(0);
	ItemStack stack1=new ItemStack(ElectronicaEngineered.siliconGrindingItem,2);
	if(tileEntityGrinder.getStackInSlot(0).stackSize>=0)
	{

					tileEntityGrinder.getStackInSlot(0).stackSize--;
					if(tileEntityGrinder.getStackInSlot(1)==null)
					{
						tileEntityGrinder.setInventorySlotContents(1,stack1);
					}
					else
					{

						tileEntityGrinder.getStackInSlot(1).stackSize+=2;
						System.out.println(tileEntityGrinder.getStackInSlot(1).stackSize);
						System.out.println(stack0.stackSize);
					}



	}

tried adding an if statement:

if(tileEntityGrinder.getStackInSlot(0).stackSize>=0)
	{

					tileEntityGrinder.getStackInSlot(0).stackSize--;
					if(tileEntityGrinder.getStackInSlot(1)==null)
					{
						tileEntityGrinder.setInventorySlotContents(1,stack1);
					}
					else
					{

						tileEntityGrinder.getStackInSlot(1).stackSize+=2;
						System.out.println(tileEntityGrinder.getStackInSlot(1).stackSize);
						System.out.println(stack0.stackSize);
					}


				if(tileEntityGrinder.getStackInSlot(0).stackSize==0)
				{
					tileEntityGrinder.setInventorySlotContents(0,null);

				}
	}
