length field in Object Class <p>Sorry if this question have been asked before. I have some doubts regarding length field of Object class. Correct me if i am wrong, Every class impilcitly extends Object class thats why we can access every methods like equals,clone,hashcode etc</p> <p>So my question is when we create any array for example array of int[] ,foo[] we can access length field of Object class but when we create any object we can not see length variable, why?</p>
