Pleas work with me step by step to cread code using java language-Drjava8.

For this project I will continue to work with files.I want the file format will be similar to a source code program.And I will tokenize the contents.Put tokenizing for recognizing the value of each component of a source program by classifying eachtoken.

I am required to Create methods to perform the identification of punctuation, integer constants, floating point constants, reserved words and identifiers. LikeisPunct,isIntegral,isDouble,isReserved,isIdentifier. In addition,from the five methods I noted above,I would create one more method calledclassifywhich is responsible for taking theStringtoken and printing its classification and value. Using a new standard class calledPattern, So I will be able to identify certain patterns in strings.

Thanks for help.

Punctuation "\\p{Punct}" Integral "\\d+" Floating "\\d+\\.\\d+" Identifier "[a-zA-Z]+[0-9a-z_]*" 

int double long if else void while for return 

I will be Using the following test file as my source:

int x ; int y = 35 ; for ( x = 0 ; x < 10 ; x ++ ) { y = y * 3.14 ; } 

As my instructor said, my program would have outcome as these below:

RESERVED int IDENT x PUNCT ; RESERVED int IDENT y PUNCT = INTCONST 35 PUNCT ; RESERVED for PUNCT ( IDENT x PUNCT = INTCONST 0 PUNCT ; IDENT x PUNCT < INTCONST 10 PUNCT ; IDENT x UNKNOWN ++ PUNCT ) PUNCT { IDENT x PUNCT = INTCONST 35 PUNCT * DBLCONST 3.14 PUNCT ; PUNCT }
