If you did not write an equals$0$ method for a class, and then tried to call the equals method on an object of that class. what would happen?

Select one:

Java would throw a compiler error, the equals method does not exist.

Java would use the default equals method, which uses $\text{'}==\text{'}{?}^{on}$ both objects.

Java would use the default equals method, which compares the objects' fields.

None of these are correct.
