Convert the lexical analyzer (which is written in C) given in Section 4.2 of the book to Java, and it to recognize the following list of reserved words and return their respective token codes: for (FOR_CODE, 30), if (IF_CODE, 31), else (ELSE_CODE, 32), while (WHILE_CODE, 33), do (DO_CODE, 34), int (INT_CODE, 35), float (FLOAT_CODE, 36), switch (SWITCH_CODE, 37).

Code in Section 4.2 is :

/* front.c-a lexical analyzer system for simple arithmetic expressions / #include #include /*Global declarations* /* Variables / int charClass; char lexeme [100]; char nextChar; int lexLen int token; int nextToken; FILE *in fp, *fopen () /* front.c-a lexical analyzer system for simple arithmetic expressions / #include #include /*Global declarations* /* Variables / int charClass; char lexeme [100]; char nextChar; int lexLen int token; int nextToken; FILE *in fp, *fopen ()
