3. Basic knowledge in Design Patterns

Lab 1

Objective: To acquire basic skills in using the XML language. Study of the structure of a typical software project, formats of standard project description files. Study of JAR format. Gaining skills in using tools to automate the process of assembling software projects in Java - Apache ANT (Another Neat Tool).

General Task:

1. Learn the syntax and structure of the XML language. Be able to edit XML files in a text editor.

2. Get acquainted with the purpose and structure of JAR archives. Be able to create JAR archives and run Java classes from the JAR archive using command line tools.

3. Get acquainted with the means of automating the collection of ANT projects. Examine the purpose and structure of the build.xml file, its structural components - goals, objectives, dependencies, etc.

4. Get acquainted with the directory structure of a typical project, XML-files of the project description (.project, .classpath, build.xml).

5. Modify the build.xml file so that it has all the necessary goals, freely know the purpose of each goal.

Main Task: Delete from the project all files with extensions .tmp, .jar, .class except those starting with the letter "a".

Lab 2

Objective: Introduction to the types of UML charts. Gaining basic skills in using a UML class diagram. Gaining skills in the use of automation tools for UML modeling.

General Task:

1. Get acquainted with the purpose and types of UML diagrams. To study the diagram of classes, to own elements and relations between them freely. Be able to build class diagrams for Java source code, as well as generate raw code equivalent to a given class diagram.

2. Construct a class diagram containing three interfaces If1, If2, If3 with methods meth1(), meth2(), meth3()and classes that implement them Cl1, Cl2, Cl3, respectively.

3. According to the option to implement the generalization and aggregation relations on the class diagram.

4. The implementation of methods should display the class name and method name on the console).

5. Get acquainted with the means of automation of UML-modeling.

Main Task:

Generalization: If1 <- If3; If3 <- If2; Cl1 <- Cl2

Aggregation: If1 <- Cl3; Cl1 <- Cl2; Cl1 <-Cl1

Lab 5

Objective: Introduction to the types of software design templates. Study of behavioral design patterns. Gain basic skills in using Iterator, Mediator and Observer templates.

General Task:

1. Examine behavior patterns for software design. Know the general characteristics of behavior patterns and the purpose of each of them.

2. Examine in detail the behavior patterns for software design - Iterator, Mediator and Observer. For each of them:

   • study the template, its purpose, alternative names, motivation, cases when its use is appropriate and the results of such use;
   • know the features of the template, related templates, known cases of its use in software applications;
   • be fluent in the structure of the template, the purpose of its classes and the relationship between them;
   • be able to recognize a template in a UML class diagram and build raw codes of Java classes that implement the template.

3. Develop interfaces and classes that implement tasks (according to the option) using one or more templates. Fully implement the methods related to the functioning of the template in the developed classes.

Main Task: Define class specifications that encapsulate a linear list of integers and implement the possibility of normal sequential traversal and sequential traversal in an ordered structure.

To implement this lab was used Iterator pattern.

Lab 8

Main Task: Define class specifications for the implementation of the composite and its iterators - to bypass the structure by depth search methods (DFS) and breadth (BFS).
