What Is Accessor?

Accessor methods are like the best kind of house guest. They're there when you need them, they don't make a mess, and they're always happy to help with whatever you need. When you want to get at some data hidden in an object, but you don't know what it is or how to access it, an accessor method can be the key. These methods give you a way to "get" your data by name or key instead of digging into an object's whole structure. Accessor methods are also getters and setters because they let you get or set properties on objects. Your code can call these public methods from anywhere in the program, providing a nice abstraction layer that allows different parts of your program to communicate without worrying about how those parts are implemented. In object-oriented programming, a dependent code is contained within accessor methods. These accessors directly access state data, so there's no need to change them when you implement a new dependent code. This is an advantage of this type of object-oriented programming. When comparing two data items, two access method calls are necessary in order to make the comparison. The first step is to find the data creator. There are two approaches: either you can look for a reference to that object, or you can look for an instance of the class by name. If you choose the latter option, you must ensure that your class name is unique across all your classes to avoid errors. Once you have found your data creator, call its new method and create an instance of it. Now, that you have an object call its accessor methods and compare those values with your second data item or object. You can do this manually or use a loop so that all those values are automatically compared in one go.
