Consider the grammar of expressions provided in file `grammar.txt`.

Write a parser for the given grammar. The parser will use the scanner (written in project 1) to process a file and return true or false, depending on whether the input is syntactically correct according to the given grammar.

(Written in Java)

Note: Your program should be well commented and include information about how to execute it.

The following are links for the code and text files.

scanner: Project 1 Code: https://hastebin.com/ilekepeyul.cs

Grammar.txt. : https://hastebin.com/uzojosivac.sql

testRead.txt: https://hastebin.com/nexunezubo.coffeescript

So, basically I need my project that i wrote to be able to " return true or false, depending on whether the input is syntactically correct according to the given grammar".

the parser should be written in JAVA
