[1.12.2] how to add lore to an item

[madmagic]

1st of all, i dont know annything about java because i will only ever use it for this one mods that im making, i've just been following tutorials online, mainly loremasters tutorial.

so far all i have is 1 item called comrade , and the item has a class that extends the itembase:

this is what i got so far because of what tutorials told me to do, but now i want to add a lore to the item, i seached alot but i cant find anny tutorial that tells how to do so, some other forums here said to use:

public void addInformation(ItemStack par1ItemStack, EntityPlayer par2EntityPlayer, List par3List, boolean par4) {

par3List.add("lore");

}

but i get alot of errors:

Multiple markers at this line
	- EntityPlayer cannot be resolved to a type
	- Syntax error on token ",", ; expected
	- Syntax error on token "(", ; expected
	- void is an invalid type for the variable 
	 addInformation
	- Syntax error on token ",", ; expected
	- Syntax error on token ")", ; expected
	- Syntax error on token ",", ; expected

i have no idea what they mean but i assume this is an outdated way because it was from a post in 2013. so if annyone can tell me how to do it, or provide me with a screenshot/tutorial.

thanks

Those errors are syntax errors, and are caused by not writing Java correctly.

They did not occur because the tutorial is outdated.

 

To fix such errors, please learn Java.

You haven't imported the class.

Fix this and the other errors will probably go away.
