A property is one embodiment of encapsulation in an object-oriented language, and setting a property in a custom class is equivalent to defining a private variable, a setter method, and an accessor (getter method), where the definition of the variable is The Declaration and implementation of the method is automatically generated by the system and is managed and optimized accordingly, without the need for de
