I used private to identifier for textfields but it gives error on every button and textfields and I checked the names at design, same name. Funny thing is I runned the code before it gives these error and it started with no error after closed the run, it gives these error. Also it gives illegal start of expression and class enum expected errors after the jTextField4ActionPerformed method. Any help will be appreciated
