Detailed explanation-1: -Parser Generators They take in a grammar as input and produce Java code to parse input. And they can handle more grammars than a recursive descent parser can. There is much more to building parsers than we can cover in this course.
Detailed explanation-2: -Parsing, syntax analysis, or syntactic analysis is the process of analyzing a string of symbols, either in natural language, computer languages or data structures, conforming to the rules of a formal grammar. The term parsing comes from Latin pars (orationis), meaning part (of speech).
Detailed explanation-3: -The parser or syntactic analyzer obtains a string of tokens from the lexical analyzer and verifies that the string can be generated by the grammar for the source language. It reports any syntax errors in the program. It also recovers from commonly occurring errors so that it can continue processing its input.
