How to fill out setter method

How to fill out a setter method:

1. Start by declaring the setter method in your class. The method name should follow the convention of "set" followed by the capitalized name of the property you want to set. For example, if you have a property called "name", the setter method should be named "setName".
2. Add a parameter to the setter method that represents the value you want to set for the property. This parameter should have the same data type as the property.
3. Inside the setter method, assign the value passed to the parameter to the property. This can be done using the assignment operator (=). For example, if your property is named "name" and the parameter is named "newName", the assignment would be "this.name = newName;"
4. Determine if any additional processing or validation is required before setting the value. You can add conditional statements or perform operations based on the value being set. This step is optional but can be useful if you need to enforce certain rules or constraints.
5. It is good practice to include any necessary documentation or comments to explain the purpose and usage of the setter method. This can help other developers understand the code and provide clarity.

Who needs setter method:

1. Classes or objects that have properties that need to be modified or updated from outside the class itself may require a setter method. Setter methods provide a way to encapsulate the property and control access to it.
2. Developers who are designing classes or APIs for other developers to use may also need to include setter methods. By providing setter methods, developers can define how the properties should be set and enforce any necessary validation or processing.
3. Setter methods can be useful when implementing the principle of encapsulation in object-oriented programming. Encapsulation allows for better control and organization of the code by keeping the internal state of an object hidden and providing access to it through methods, such as setter methods.
