How to determine an object's class?

Question

If class B and class C extend class A and I have an object of type B or C, how can I determine of which type

Answer 1

I use the blow function in my GeneralUtils class, check it may be useful

    public String getFieldType(Object o) {
    if (o == null) {
        return "Unable to identify the class name";
    }
    return o.getClass().getName();
}
