You call the class constructor which is exactly the same as the class name, followed by the respective namespace, pass the required arguments (if any), and that’s it.
The scenario described above is exactly what happens in nearly all situations. But there is a condition where exceptions may arise: whenever you try to instantiate a class dynamically.
Forms are often a nightmare on mobile. We can make the process as pain-free as possible by reacting to context. Input fields that expect numerical values should have a numerical UI. Bringing up a number keyboard on small screens is easy on most platforms — just use a
