Home Task #3

Requirements for Home task #3

Requirements	Implementation
Create at least 10 classes	Created different types of phone brands
All classes must contain properties	Each phone brand contains unique feature
Create at least 10 classes	Created different types of phone brands

All private variable must have getters and setter methods	All classes contain getters and setters methods
All classes should have at least one custom constructor	Constructors for each class call different variables

Create separate class with main() which will instantiate objects of implemented classes.

Home Task #4

Requirements for Home task #4

Override methods from class Object (toString(), hashcode(), equals()) for at least 3 classes from the hierarchy.	Classes Samsung, Xiaomi, Motorola uses the toString() to override a method

Home Task #5

Requirements for Home task #5

Requirements	Implementation
Add 5 interfaces to the existing hierarchy	apple, lg, nokia, sony, & phone classes
Use polymorphism with the abstract class and interface from the hierarchy.	connectToWifi() -> Apple -> Phone -> interfaces.com.solvd.laba.Connectivity
Create final class, method, variable	Xiaomi class
Create a static block, method, variable	Huawei class

Home Task #6

Requirements for Home task #6

Requirements	Implementation
Create 5 custom exceptions	Created a PhoneExceptions class with 5 custom exceptions under exceptions package
Handle exceptions in 2 ways	1. InputSelectionException is handle by try catch block in BrandSelection for user input 2. ModelNotFoundException is handle by throws keyword on Phone class
Use try-catch with resources	Used the InputSelectionException and try-with-resources to end program
Log messages to the console, file	Used LOGGER.info.severe.warning to prompt multiple statements

Home Task #7

Requirements for Home task #7

Requirements	Implementation
Add 5 collections to the hierarchy	Created a class PhoneCollections and used it to prompt the different child classes phone specs Map,List and Set collections used for Apple, LG, Sony
Use polymorphism with the abstract class and interface from the hierarchy	connectToWifi() -> Apple -> Phone -> interfaces.com.solvd.laba.Connectivity
Create custom implementation of LinkedList with generic and use it in your project	Added the generic class CustomLinkedList and use it to implement a LinkedList in the com.solvd.laba.PhoneMenu class

Home Task #8

Requirements for Home task #8

Requirements	Implementation
Move all projects to Maven	moved project into maven repository
Build jar file and deploy to the local repository	SNAPSHOT.jar file in the target folder
Add and use 2 Plugins	Added log4j-core & log4j-api and then commons-lang3 & commons-io
Run mvn for different phases from the Maven lifecycle. Check the result.	Used clean, validate and deploy

Home Task #9

Requirements for Home task #9

Requirements	Implementation
Read text from the file and calculate the numbers of the unique words	Created a text file phone_Information.txt
Write the result to the file	Output file is called phone_colors_unique_words.txt
com.solvd.laba.Main requirement is: using StringUtils and FileUtils to implement it with minimum lines of code	com.solvd.laba.UniqueWordCounter StringUtils and FileUtils StringUtils is used to split the content of the input file into wordsli> FileUtils to read the input file contents into a string & write number of unique words in a file

Home Task #10

Requirements for Home task #10

Requirements	Implementation
Use at least 5 lambda functions from the java.util.function package	Used Consumer in the PhoneProcessor Used Function in the PhoneNameConverter class Used Predicate in the BandFilter class Used Supplier in the PhoneNumberGenerator
Create 3 custom Lambda functions with generics	CustomLambdaSupplier -> CustomLambdaPhoneCarrier CustomLambdaPredicate -> CustomLambdaOrigin
Create 5 complex Enums(with fields, methods, blocks	Created 3 complex Enums with field variables, methods and block CameraTypeEnum, DisplayTypeEnum, PhoneColorEnum

Home Task #11

Requirements for Home task #11

Requirements	Implementation
Add 7 collection streaming in the hierarchy with terminal and non-terminal operations	Package Stream added it contains 7 classes with terminal and non-terminal operations to used in the program Terminal Operation: collect, count, anyMatch, findAny Non-Terminal Operations: filter, map, sorted
Handle exceptions in 2 ways	1. InputSelectionException is handle by try catch block in BrandSelection for user input 2. ModelNotFoundException is handle by throws keyword on Phone class
Using reflection extract information(modifiers, return types, parameters, etc) about fields, constructors, methods. Create object and call method using the only reflection	Created a reflection class PhoneReflection to extract information from constructors fields and methods from Samsung class
Log messages to the console, file	Used LOGGER.info.severe.warning to prompt multiple statements

Home Task #12

Requirements for Home task #12

Requirements	Implementation
Create 2 Threads using Runnable and Thread	Package thread 2 threads PhoneThread and PhoneRunnable to implement threads
Create Connection Pool. Use collection from java.util.concurrent package. Connection class may be mocked. The pool should be threadsafe and lazy initialized.	ConnectionPool has a size of 5 and uses singlenton thread
Initialize Connection Pool object of size 5. Load Connection Pool using single threads and Java Thread Pool (7 threads in total)	Connection class and also created the DemoConnectionPool class to demonstrate usage
5 threads should be able to get the connection. 2 Threads should wait for the next available connection. The program should wait as well	Connection class and also created the DemoConnectionPool class to demonstrate usage
Implement previous point but with interfaces Future and CompletableStage	ConnectionPool class as well as DemoConnectionPool class implement all three tasks on Connection pool, refer to comments in both classes

Home Task #13

Requirements for Home task #13

Requirements	Implementation
Build hierarchy for Schema from the below course	DAO and Model hierarchy classes have been created
Create DAO classes with necessary interfaces, abstract classes, and Generics. DAO should be scalable and flexible to support another framework and another database as well. All CRUD operations should be supported using JDBC. Use connection pool from the below block	dao, model, and services packages; dao contains jdbc package with DAO implementaion class with a generic DAO interface, model package contains all Model classes, and services contains implementations package has well has Generic Services
Implement Service layer with necessary abstraction to be able to switch between databases and frameworks	Service package -> Generic Services interface & implementation package with Services for classes.

Home Task #14

Requirements for Home task #14

Requirements	Implementation
Create one XML file and XSD schema for at least 5 classes from the below hierarchy	Added XML and XSD that contains 5 classes: Brands,Countries,OperatingSystem,Phones,and UserAccounts
Validate XML file using XSD schema and assigned parser	Used validateXMLAgainstXSD, SchemaFactory, and the validator classes to perform the validation process
Parse XML file using one of the parsers from the title	The com.solvd.laba.ParserRunner clas parsers the XML file using the DocumentBuilder class.

Home Task #15

Requirements for Home task #15

Requirements	Implementation
Add JAXB annotations to the hierarchy. Date, List, and complex objects should be covered	Added JAXB annotations to the model hierarchy date is being handle by Brand Model as Phone Brand Foundation Date and list is handle by Phone Model for Phone Features every other complex objects is from other classes
Parse XML using JAXB	The JAXBParserRunner class uses the JAXBContext class to create a JAXB context for the PhoneData class: JAXBContext and other methods such as unmarshall; Unmarshaller jaxbUnmarshaller = jaxbContext.createUnmarshaller();

Home Task #16

Requirements for Home task #16

Requirements	Implementation
Create one Json file for at least 5 classes from the hierarchy.	phone.json file is under resources with 5 classes: Brand, Country, OperatingSystem, Phone, User Accounts
Add Jackson’s annotation to the hierarchy. Date, List, and complex objects should be covered.	Model classes have Jackson's annotation in the hierarchy. Brand covers dates, Phone covers list by phone features
Parse JSON using Jackson	JSONParserRunner parse the JSON file by using Jackson by using object mapper
