Hello, here I bring the Property class, but just udpated. PropertyFile PF = new PropertyFile(); Here, you create the PropertyFile. PF.setFileRoute(ROUTE); Here, you add the file route to the property. PF.setProperty(NAME, VALUE); Now, you add a property to the file. PF.getProperty(NAME); Here, you get a property key from the file. PF.getFullProperty(NAME); Here, you get a property from the file, but with the name=value.
