Getters and Setters

Getters and Setters are methods used in properties to control the access to private data members (fields) of a class. Getters are used to retrieve the value of a property, while setters are used to assign a new value to the property. Getters and setters provide a way to encapsulate the access to data and enable additional logic or validation to be executed.

Here's an explanation of getters and setters with code examples:

Getters:

• A getter is a method that retrieves the value of a property.

• It is defined using the get keyword in a property declaration.

• Getters do not have parameters and return the value of the property.

Example:

public class Person
{
    private string name; // Private field

    public string Name // Property
    {
        get { return name; } // Getter method
    }
}

Person person = new Person();
string personName = person.Name; // Accessing the property using the getter

In the above example, the Name property has a getter that returns the value of the private name field. The getter allows external code to access the value of the property without directly accessing the underlying field.

Setters:

• A setter is a method used to assign a new value to a property.

• It is defined using the set keyword in a property declaration.

• Setters have a single parameter representing the new value to be assigned to the property.

Example:

public class Person
{
    private string name; // Private field

    public string Name // Property
    {
        get { return name; } // Getter method
        set { name = value; } // Setter method
    }
}

Person person = new Person();
person.Name = "John"; // Setting the property value using the setter

In the above example, the Name property has both a getter and a setter. The setter allows external code to assign a new value to the property, which internally updates the private name field.

Getters and setters allow controlled access to properties and enable additional logic or validation to be executed during property access or assignment. They provide a way to encapsulate data and maintain the integrity and consistency of the underlying values.
