The code gives this error

Input string:

Exception in thread "main" java.util.NoSuchElementException: No line foundat java.base/java.util.Scanner.nextLine(Scanner.java:1651)at TMSimulator.main(TMSimulator.java:15)

so what I'm doing is reading in an input string, for the purposes of this example Ill be using 11 from here I use a file handler, read in first id line and then second all it does is put numStates and stopping states into seperate integers so now i have 1 inputs. next, I try to split all the data into lines seperated by the next line delimiter; however i dont know how to handle multiple ,test things in the array and i know eventually using ; isnt whats needed.

i am thinking two things: making an nested array with every combination of [][] into my file path, or doing a method that reads line by line and splits them to only seperate at each empty space in string however... how is it possible to have a case filed variable and a loop together.

2nd idea: my tm has states, so using an indented num can be considered like e and 0 however i would need to preserve some sort of ordering system maybe ascii values?

however when i want to make sure the correct state is being accepted then i will say m = (state1 = 1) < 2; brainf*rk type?
