That’s the definition of an abstract class. You cannot<\/em> create an instance of it, only a type derived from it.<\/p>\n

Think of something like a fruit. You cannot have a fruit<\/em> sitting on the table. It must<\/em> be a certain type<\/em> of fruit, such as an orange or an apple. In this case, fruit<\/em> would be an abstract class, and can implement functionality and properties common to all fruit. Orange<\/em> and Apple<\/em> would derive from the Fruit<\/em> class, and implement functionality and properties specific to that type<\/em> of fruit.<\/p>\n

Use the abstract<\/code> keyword when it does not make sense to create an instance of your class, but you want to implement base functionality that can be shared across derived types. If you simply want to define a contract without any<\/em> shared code, you’d use an interface.<\/p>\n<\/p><\/div>\n
