在JRuby中投射对象

import java.lang.reflect.Constructor;

public class Main {
    public static void main(String[] args) {
        Person person = new Person("John");
        Employee employee = (Employee) castObject(person, Employee.class);
        System.out.println(employee.getName());
    }

    public static Object castObject(Object object, Class<?> targetClass) {
        try {
            Constructor<?> constructor = targetClass.getConstructor(object.getClass());
            Object targetObject = constructor.newInstance(object);
            return targetObject;
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
}
