L'erreur que me retourne Eclipse :
Exception in thread "main" java.lang.NullPointerException
at tests.CopyOfProgramme_final.findFiles(CopyOfProgramme_final.java:42)
at tests.CopyOfProgramme_final.main(CopyOfProgramme_final.java:118)
Sachant que la ligne 42 est celle ci :
cell.getNumericCellValue();
Sachant que la ligne 118 est celle ci :
finder.findFiles("C:/test2");
Merci de votre aide ...
