Abstract Classes: Coding Abstract classes cannot be instantiated Instantiate (v ) – use the “new” keyword to create new Object (or instance of a class) Some methods remain unimplemented Subclasses must implement all abstract methods or must also be abstract classes Why make a method abstract?
Chapter 11 Abstract Classes & Interfaces - CCSU
You cannot instantiate (construct instances of) an interface If a class implements an interface it must provide bodies for all methods otherwise it must be an abstract" class (more later) An interface can extend other interfaces A class can extend only one class but it can implement many interfaces 5

abstract Java Keyword The abstract keyword may modify a class or a method An abstract class can be extended (subclassed) but cannot be instantiated directly An abstract method is not implemented in the class in which it is declared but must be overridden in some subclass Examples public abstract class MyClass {} public abstract String

Abstract class in Java - BASPONC College
An interface in java is a blueprint of a class It has static constants and abstract methods The interface in java is a mechanism to achieve abstraction There can be only abstract methods in the java interface not method body It is used to achieve abstraction and multiple inheritance in Java
Chapter 11 Abstract Classes & Interfaces - CCSU
The recommended Java solution in this case is an abstract class You can put abstract in an instance method heading if you replace the method's body by a semicolon T his makes the class it is in an abstract class You must also put abstract in the class heading to signal this
Can class methods in an abstract class be abstract?
- Class methods in an abstract class cannot be abstract. Ø The heading public interface X means X cannot contain anything but non - final instance method headings (with a semicolon in place of the body) and final class variables. A non -abstract object class with the heading class Y implements X must define all methods in that interface .
How does a non-abstract object class implement X?
- A non -abstract object class with the heading class Y implements X must define all methods in that interface . A class may implement many interfaces (use implement X,U,Z ) but may subclass only one class. Ø The compiler binds a method call t o a particular method definition when it can, namely, for a class method or for a final instance method.
How do I put abstract in an instance method heading?
- You can put abstract in an instance method heading if you replace the method's body by a semicolon. T his makes the class it is in an abstract class. You must also put abstract in the class heading to signal this. Any concrete class that extends the abstract class must have coding for each of the abstract methods.
Can you extend an abstract class with a concrete class?
- Any concrete class that extends the abstract class must have coding for each of the abstract methods. Reminder: A method call is polymorphic if at runtime the call could execute any of several different method definitions (i.e., codings). You cannot have an abstract class method, because class methods cannot be overridden.
