كيف اجعل أن new Meter reading تكون اكبر منold Meter Reading و قيمة unpaid Balance أكبر من الصفر
|
New Meter Reading أكبر من Old Meter Reading ،،
كود PHP:
Scanner in6=new Scanner(System.in);
System.out.println("Enter New Meter Reading:");
NewMeterReading = in6.nextInt();
if (NewMeterReading < OldMeterReading){
System.out.println("New meter reading cannot be less than old meter reading");
System.out.println("Enter New Meter Reading again:");
NewMeterReading = in6.nextInt();}
Unpaid Balance ،،
كود PHP:
Scanner in8=new Scanner(System.in);
System.out.println("Enter any unpaid balance:");
unpaidbalance = in8.nextDouble();
if (unpaidbalance<0){
System.out.println("Unpaid amount cannot be less than zero");
System.out.println("Enter any unpaid balance again:");
unpaidbalance = in8.nextDouble();}
لو حاولت فيها كان عرفت ببساطة
