Python Numerical Literal Checker

A Java-based implementation of a NFA design that recognizes Python numeric literals (decinteger, octinteger, hexinteger, floatnumber) based on Python's 3.14.0 Documentation.

Getting Started

Compile and run the program with the following commands

javac -d out $(find src -name "*.java")
java -cp out Main

Features

After running the program, you will be prompted to either:

1. Input a string

   Enter test cases individually and see their respective results

2. Run Test File

   By default, reads tests/in_ans_combined.txt and outputs the results in tests/out_combined.txt.

   To change the input file, please modify line 61: String inputFile = "tests/diff_input.txt";.

• Designed JFLAP diagrams for the required integers and floatnumbers: py-floats.jff and py-integers.jff
• Improved JFLAP diagram of combined required integers and floatnumbers: py-combined.jff
• Implemented NFA logic in the automata package, containing classes that define a NFA such as its states and transitions
• Implemented FloatNFA.java that defines the NFA for floatnumbers

• Designed JFLAP diagram that combines the required integers and floatnumbers: py-combined.jff
• Implemented I/O logic in the io package, containing classes that read from a test file and write to a results file
• Implemented CombinedNFA.java that defines the NFA for both the required integers and floatnumbers
• Implemented Main.java to provide user interaction with program
