1. Lexical analyzer

• directory name : mid
• lexical analyzer for a simplified Java programming language
• Based on specification(by class note), define tokens (e.g., token names) for a simplified Java language, make regular expressions which describe the patterns of the tokens, construct a NFA for the regular expressions, translate the NFA into a DFA, especially in the form of a table, and implement a program which does a lexical analysis (recognizing tokens).

2. Syntax analyzer

• directory name : final
• a bottom-up syntax analyzer (a.k.a., parser) for a simplified Java programming language
• Implement a SLR parsing program for the simplified Java programming language by using the constructed table.

1. Open the Project directory(mid) that you want to execute.
2. On a command line, your analyzer must run with the following command.

$ python3 lexical_analyzer.py <input_file_name>.java

3. Input: A program written in a simplified Java programming language
4. Output: <input_file_name>.out

1. Open the Project directory(final) that you want to execute.
2. On a command line, your analyzer must run with the following command.

$ python3 lexical_analyzer.py <input_file_name>.java

$ python3 syntax_analyzer.py <input_file_name>.out

3. Input: An output of your lexical analyzer program
4. Output: just an acceptance message;(If an output is “reject”) please make an error report which explains why and where the error occurred (e.g., line number)
