# Remove Setting Method

> Problem: The value of a field should be set only when it’s created, and not change at any time after that. Solution: So remove methods that set the field’s value.

## Problem

The value of a field should be set only when it’s created, and not change at any time after that.

## Solution

So remove methods that set the field’s value.

## Why Refactor

You want to prevent any changes to the value of a field.

## How to Refactor

1. The value of a field should be changeable only in the constructor. If the constructor doesn’t contain a parameter for setting the value, add one.
2. Find all setter calls.

  * If a setter call is located right after a call for the constructor of the current class, move its argument to the constructor call and remove the setter.
  * Replace setter calls in the constructor with direct access to the field.
3. Delete the setter.
