Design pattern to convert a class to another [closed]

Question

I have a class called GoogleWeather, I want to convert it to another class CustomWeather.

Is there any design pattern which helps you to convert classes?

Answer 1

In that case I'd use a Mapper class with a bunch of static methods:

public final class Mapper {     public static GoogleWeather from(CustomWeather customWeather) {       GoogleWeather weather = new GoogleWeather();       // set the properties based on customWeather       return weather;    }     public static CustomWeather from(GoogleWeather googleWeather) {       CustomWeather weather = new CustomWeather();       // set the properties based on googleWeather       return weather;    } } 

So you don't have dependencies between the classes.

Sample usage:

CustomWeather weather = Mapper.from(getGoogleWeather());
