How to copy superclass object values to subclass object values?

Question

I want to copy superclass object getters to subclass object setters. But how can I do this easily. I\'m looking for something like clone. Could you please me help me to find it?

Don't use your own code, when there are special libraries. I use modelMapper (http://modelmapper.org/).

public class AppsUtil {

    private static ModelMapper mapper = new ModelMapper();

    public static ModelMapper getMapper() {
        return mapper;
    }

    static {
        // full matching of names in classes
        mapper.getConfiguration().setMatchingStrategy(MatchingStrategies.STRICT);
    }

Then use AppsUtil in your constructor in child class:

@Getter
public class AppsEmailException extends AppsException {

    /**
     * email, на который не отправилось сообщение
     */
    private String email;

    public AppsEmailException(AppsException baseClass, String email) {
        AppsUtil.getMapper().map(baseClass, this);
        this.email = email;
    }
}
