La clase funciona perfectamente, pero yo necesito integrala en mi código. Osea mandarle yo el "String pdfFile = "C://prueba.pdf";" mandarle yo ese valor desde otra clase, pero no se como hacerlo ya que coge los arg de arriba en main y no se como hacerlo...
por favor me podéis indicar como debo hacer para que yo el mande a esta clase el string con la ruta del pdf que quiero extraer el texto.
Muchas gracias.
