• a Scheme program in the file boolsimp.ss equivalent to the Java program that you are required to write;
• a Java "stub" file boolSimp.dj1 that defines a composite hierarchy of "abstract syntax" tree classes rooted in the class Form representing boolean expresssionsexpressions;
• a Java library file Parser.java contain a class Parser with
  • a read() method that reads a boolean expression represented in "Scheme form" and returns the corresponsing Java Form abstract syntax tree and
  • a (commented out) simplify() method that composes the visitors you must write in boolSimp.dj1 to simplify whatever formula the Parser instance contains.
• a Java "stub" test file boolSimpTest.java that includes some rudimentary tests of the code in the boolSimp.dj1 stub file.

The file Parser.java includes two Parser constructors parseParser(File file) and parseParser(String form) for building parsers to parse the boolean expression (in external text form) in the specified File or String, respectively. To construct a Parser for the formula in a file {{}} you must invoke
