Make them: the idea is that you make them. Commands won't
Run them: I would have expected that Google knows, but admittedly it's not very helpful with how to install javacc.

Phase 1:
Lexical Specification part (Regular Expressions of the Tokens )
[Be Creative when you design your language]
• Identify all the basic tokens of your language in Table 1:
o arithmetic operations: addition, subtraction, power ... etc (at least 5)
o relational operations: equality, less than...etc (at least 5)
o logical operators: AND, OR, NOT... etc (at least 4)
o punctuation Marks: colon, semi-colon,....etc (as you need in your language)
o Identifiers
o Digits (integer and float)
o White Spaces: one or more spaces, Tab and new line (it should be discarded)
o Keywords (should be words not symbols. For example: for selection statements
key words use IF or if or If or When )
o Comments
o You can add other tokens as you need.
Phase 2:
• Write the grammar for your language parser using BNF notation in a word file.
o Make sure that your Grammar free of problems such as left recursion and
choice conflicts.
o Your grammar should have these statements:
• Arithmetic statements
• Relational statements
• Logical statements
• Boolean statements
• Conditional statements: if-then, if-then-else
• Two iterative statements such as for, while or do while.
• Variable Declaration: String datatype, Integer datatype and another
datatype from your choice.
• Constants declaration.
• Two data structures of your choice such as list, array.
• Then Convert the grammar into JavaCC using (in jj file).
• The jj code should display “syntactically correct statement” for the correct input
statements. Otherwise, it displays an error message.
• Add some lexical actions to the definition of some tokens or syntactic actions to the
grammar part (at least any 5 actions).
