Question about Java programming: How do I implement the 'Serializable' interface?
The assignment said for me to implement the interface into a couple of pre-existing classes we had done beforehand but when I change my class header to implement the interface, it compiles without a problem even though I did not implement any method headings.
Does this mean that the interface doesn't have any methods to define?
If so, how does this interface work if it doesn't have any possible methods?
