Question: Write a java program to recognize: Unsigned Integer (uint): unsigned integer value String Literal: (sliteral): anything that is surrounded by double quotes ( s) Whenever

  • Write a java program to recognize:
    • Unsigned Integer (uint): unsigned integer value
    • String Literal: (sliteral): anything that is surrounded by double quotes ( s)
  • Whenever any of the above tokens are matched, your project should also print the respective token name (uint or sliteral) and the attribute value (the unsigned integer value or the string literal value) after printing the lexeme.
  • If the input (source code to be compiled) to your project (compiler) contains something other than the comments, white spaces or the lexemes mentioned above or in previous project steps, then your compiler should generate and display the error with:
    • The line number
    • The unrecognized lexeme in the source code and
    • A meaningful error message
  • Add code to your project to
    • Create a symbol table to store tokens in it
    • Every time you recognize a lexeme, you need to decide whether you want to store the token in the symbol table or not and then if needed, you store it.
    • One way is to keep symbol table in the form of an array of objects that store token name, type and attribute value. (if you like you can use any other type of data structure)
    • Before exiting, your program should print out the tokens stored in the symbol table.
