How do I make a good sword in Minecraft?

I want to make a good sword in Minecraft, but I don't know in which order to do the enchantments. I screwed it up the first time and could only do 3 things on it. The best on top should be Sharpness V, Looting III, Mending, Unbreaking III and, if you like, Fire aspect II. Can someone tell me if and how you can enchant the sword?

Would be really cool.

You can also enchant a sword in an anvil with a book.

If you have Sharpness V, Looting III, Mending, Unbreaking III and Fire aspect II books, then you put the sword in the left slot of the anvil and the book in the right.

I think you always tried to enchant the sword directly with the magic table.

I know that, but I mean in which order I should do the enchantments.

It does not matter

This is how you bring it all up:

Enchant the sword in the enchantment table and try to get as many max-level enchants as possible. Unbreaking 3 Looting 3 for example.
Enchant the sword with a cheap book like Mending
Enchange the sword with a more expensive book

You can tell cheap or expensive by which book costs more when added.

If you are still missing enchantments:

Put two books together
Enchant the sword with the assembled book
