QuestionI'm attempting to verify the scanner inputs in my main method with the contents of input.txt, which contains an id, salary, and employee status number. I'm attempting to do this by reading the text file via a BufferedReader within the read() method in my main method. In this method, I validate the inputs passed through reader and return true if they match any contents of the input.txt file. If they return false by not fitting the parameters I've set, the program should halt and send a println message. However I notice that when I call it within the if statement after the scanner inputs, the program completely skips over the if statement and the read() method. I've tried experimenting around with different ideas and structure, but nothing has been successful. No matter what incorrect variables I input into the scanner, they are all allowed to pass because my code isn't calling the read() method. Is there a way to avoid this issue?
