Thanks for your code ! I need your help as follows: String controlNr1String = dataInPrint.substring(indexOfFirstSeparationMark1 + 1, indexOfSecondSeparationMark2); String controlNr2String = dataInPrint.substring(indexOfFirstSeparationMark1 + 1, indexOfSecondSeparationMark2);
What does "controlNr1String" and "controlNr2String" mean?
Looking forward to your reply!
