Recursive Descent subprogram with EBNF rule, using  Java syntax (syntax)

Type (Recursive-Descent Subprogram):

<while_loop> -> while (<condition>) <statement>;<br>The lex method to be used reads a single lexeme, and the lexemes' token code is in the nextToken variable.<br>is to the left. Suppose that the defined tokens are respectively:<br>while - WHILE_CODE<br>left parantex - LEFTPAREN_ CODE<br>right parenthesis - RIGHTPAREN_CODE<br>semicolon - SEMICOLON_CODE<br>If any error is caught, create the function that calls the error function.<br>

Extracted text: -> while () ; The lex method to be used reads a single lexeme, and the lexemes' token code is in the nextToken variable. is to the left.
