I am trying to make my program read and edit text. I was trying to use the Position=find ( String , 0 ) method but I get the error:
The method "find" isn't declared in the current class.
I have tried different classes but I cant find the correct one. Which would that be? How may I find the correct class in the future?
Thanks in advance.
The find is in the String class.
From the documentation:
int find ( String what, int from=0 )Finds the first occurrence of a substring. Returns the starting position of the substring or -1 if not found.
So what happens?
When you do Position = find(String, 0) You are calling find from which ever class your code is inside, not from String.
Furthermore, I only see one String there… Which String do you want to find in which one? You need two. Yes, find only takes one String, but it is an instance method, not a static method. You are meant to call it on the one you want to search, like this:
var position := string_in_which_you_are_looking.find(string_you_are_looking_for, 0)
