Samples of characteristics are the period of a sequence, how big a beneficial font, this new caption of a window, title regarding a customer, and so on. Attributes is actually an organic extension off sphere-both are called participants with related brands, additionally the sentence structure to have being able to access sphere and you may functions is similar. But not, in lieu of industries, attributes don’t signify sites locations. Instead, features has actually accessors that indicate the latest statements to get executed when its viewpoints is read otherwise written. Services for this reason provide a process to own accompanying measures for the discovering and writing regarding an enthusiastic object’s qualities; furthermore, they allow such as services become computed.
