Project #2
Grading: Each project will be graded on the scale 100.
Coffee Language Parse (100 points): Given the previous description of the Coffee language
(CoffeLanguage_Syntax.pdf) you are asked to implement the parser. You are expected to use ShiftReduce parser. Your output will be the string representation of a parse tree. Tokenization should be
done by your previous project. You should implement your own tree structure to build your parse tree.
You will combine your previous project with the code provided and complete the Parser class.
The only file that you are required to modify is “Parser.java” and “Lexer.java”.
