In this assignment, you must create aNetbeans Java program that:
- prompts the user for a file location (use JFileChooser)
- reads a deterministic finite automata (DFA) from a text file(see format below),
- displays to the user the alphabet associated with the DFA thatwas read
- prompts the user for an input string (use JOptionPane),
- displays whether the DFA accepts the user’s input string (useJOptionPane).
- as Java comments give the Big-O analysis of the fileInput andrun methods
- as a separate file, submit the DFA file you “unit” testedon.
Minimally, your program must implementthe following domain model (additional classes and method will berequired),
The input file containing the DFA
