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 |
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 FileUtilsStringUtils 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 |
| |
Requirements for Home task #10
| Requirements | Implementation |
|---|
| Use at least 5 lambda functions from the java.util.function package | Used Consumer in the PhoneProcessorUsed Function in the PhoneNameConverter classUsed Predicate in the BandFilter classUsed Supplier in the PhoneNumberGenerator |
| Create 3 custom Lambda functions with generics | CustomLambdaSupplier -> CustomLambdaPhoneCarrierCustomLambdaPredicate -> CustomLambdaOrigin |
| Create 5 complex Enums(with fields, methods, blocks | Created 3 complex Enums with field variables, methods and blockCameraTypeEnum, DisplayTypeEnum, PhoneColorEnum |
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 programTerminal Operation: collect, count, anyMatch, findAnyNon-Terminal Operations: filter, map, sorted |
| Handle exceptions in 2 ways | 1. InputSelectionException is handle by try catch block in BrandSelection for user input2. 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 |
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 |
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. |
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. |
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(); |
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 |
Requirements for Home task #17
| Requirements | Implementation |
|---|
| Add MyBatis DAOs to the existing hierarchy with the same requirements. Choose any XML or interface mapping. | Implementation here |
| Switch service classes to MyBatis. | Implementation here |
