Answer 2

class is like plan of future object, object is realized plan described in class, (but this image is not valid vith static part of class). Basic think in oop is group data ( variables) and functions for this data together as independend reusable code block. Then if objects is similar next think of oop is not programming new object again just use common code and add new or different feature.
