OBIETTIVI FORMATIVI

The goal of the course is to let students develop the ability to “think with objects” when designing and building a complex software system (thousands of units built by tens of programmers). At the end of the course the student should: have understood how to assign responsibility to a set of classes, have understood how to define the APIs of different units, have understood how to define abstractions and how to specify them.

Furthermore, the student should have developed practical experience in using typical programming tools, including Eclipse, Intellij, git, maven.

CONTENUTI

Abstraction types: parameterization, procedural specification, dataabstraction, type abstraction, iteration abstraction.Java basics: packages, classes, objects, variables, memory allocation, mutability. Method calls, type checking, overloading; dispatching; base types, parametric types.

Procedural abstraction: specification, contracts, pre and post-conditions, assertions, exceptions. Checked and unchecked exceptions, reflection and masking; overloading.

Data abstraction: abstract data types, abstract and concrete specification, invariants.

Abstraction of iteration: iterators.

OO Design with Card-Responsability-Collaboration. State, behavior and protocol. Single Responsibility Principle.

Abstraction on types: abstract classes, interfaces; substitution principle, equality, polymorphism, inheritance. Parametric types, internal classes, anonymous classes. Dependency inversion.

Functional programming in Java.

Design patterns: factory, builder, decorator, observer.
