TITLE Data Structures with Java Objects

LEVEL 01 - Year 1 in Modular Undergraduate Course


DEPARTMENT Computer Information Systems

DESCRIPTION This study-unit is an intensive introductory course in implementation of dynamic data structures using objects rather than plain data. Object oriented language chosen is Java but the concepts are applicable to any other object oriented language. The accent is given to the understanding of key algorithms, learning of programming techniques and writing well-designed, structured programs. The study-unit aims to cater also for students with little programming skills raising them to the desirable standard. The Java programming language is used (for the benefit of free compiler and support classes as well as a pre-requisite for later Object Oriented programming).

Topics in brief:
- Introduction to the Object Oriented paradigm (Class and Object, encapsulation, abstraction, inheritance and polymorphism);
- Case study scenario with objects, packaging and compilation of linear structures and objects;
- Recursion as a technique used for non-linear data structures;
- Dynamic data structures with objects (lists, circular lists, stacks, queues, circular queues, binary trees), heterogeneous data structures;
- Java Collections (Sets, Lists, generic collections);
- Object Streams.

The accent is given to the implementation and getting practical programming experience with the data structures rather than making them a subject of study (this will be done in different study-units).

Study-unit Aims:

To support knowledge of dynamic data structures and algorithms taught theoretically by implementing them programmatically hence being able to observe their operations. Another aim is to teach students how to manipulate objects on the dynamic data structures.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:

- Describe concept of pointers and dynamic memory as a storage for dynamic data structures;
- Explain structures and operations of dynamic data structures as well as algorithms of their typical operations;
- Understand class and object, concepts of inheritance and polymorphism;
- Understand concept of storing data structures on;
- Appreciate possibility of storing heterogeneous objects on dynamic structures;
- Learn functionality and services of standard collections and generic collectioms and be able to compare them with user created dynamic data structures.

2. Skills:

By the end of the study-unit the student will be able to:

- Develop essential, below specified, linear and non-linear dynamic structures as object oriented application programs in Java language;
- Design and implement linear dynamic structures with objects: list, circular list, stack, queue, circular queue;
- Design and implement non-linear dynamic structures with objects: Tree and Binary Search Tree;
- Create methods for population of a particular structure from the content of other (different) data structure;
- Use standard Collections and populate them with both simple data and objects;
- Store collections on Java stream (a file of objects on persistent media);
- Test the developed applications and deploy them in a modular form (packages).
