To compare two objects in a class:
A) use the == operator, e.g. object1 == object2
B) write a method to do a byte-by-byte compare of the two objects
C) write an equals method that will make a field by field compare of the two objects
D) Since objects consist of several fields, you cannot compare them

Writing an equals method that conducts a field by field comparison is the best choice for comparing two objects in a class. The == operator only compares if the two objects reference the same memory location and not if their fields are equal. Writing a byte-by-byte comparison method is usually unnecessary and less efficient. It is possible to compare objects since they consist of fields representing their state.
