السلام عليم
يوجد لدي كلاس فيه متغير ولنفرض ان اسم هذا المتغير a كيف استطيع ان اخذ القيمة النهائية لهذا المتغير و وضعها بكلاس اخر
كيف استطيع اخذ قيمة متغير من كلاس ووضعها بكلاس اخر
مغلق
شكرا اخي ابو اتلفؤاد على ردك
لقد قمت بكتابة هذا الكود
DeviceControl.setB(SerialToGsm.getc());
وعند عمل كمبايل للكود اعطى هذا الخطا
<identifier> expected DeviceControl.setB(SerialToGsm.getc()); ^ 1 error Tool completed with exit code 1
تاكد من التعاريف للميثود و نوع المتغير المرجع مطابق للمتغير الذي تريد وضعه
نص الخطا غير واضح
منقطع من حين لاخر
لقد قمت بالتاكد من تعريف الميثود
والمتغيرين من نفس النوع integer

هاذا هو كود الكلاس الاول والذي يحتوي على متغير اسمه c
