Mechanics

• Create getting and setting methods for the field.

• Find all clients outside the class that reference the field. If the client uses the value, replace the reference with a call to the getting method. If the client changes the value, replace the reference with a call to the setting method.

If the field is an object and the client invokes a modifier on the object, that is a use. Only use the setting method to replace an assignment.

• Compile and test after each change.

• Once all clients are changed, declare the field as private.

• Compile and test.
