duke-certification / java6-to-java8 Goto Github PK

Verificar como é o comando que converte o caminho no windows e ajustar o arquivo do README.

https://github.com/rcmoutinho/java6-to-java8/blame/master/README.asc#L16

Obs: @rinaldodev coloquei para você porque já deve estar usando isso na sua máquina e não tenho um windows aqui para testar :)

Perform calculations on Java Streams by using count, max, min, average, and sum methods and save results to a collection by using the collect method and Collector class, including the averagingDouble, groupingBy, joining, partitioningBy methods

Develop code that uses parallel streams, including decomposition operation and reduction operation in streams

Use Executor, ExecutorService, Executors, Callable, and Future to execute tasks using thread pools

Format dates, numbers, and currency values for localization with the NumberFormat and DateFormat classes, including number and date format patterns

criar arquivo para documentar as pessoas que se beneficiaram do projeto (quando fizeram a prova, score, etc)

Recursively access a directory tree by using the DirectoryStream and FileVisitor interfaces

Develop code that uses a method reference, including refactoring a lambda expression to a method reference

Language Enhancements: Develop code that uses String objects in the switch statement, binary literals, and numeric literals, including underscores in literals.

Language Enhancements: Develop code that uses try-with-resources statements, including using classes that implement the AutoCloseable interface.

(test yourself!)

Testes e materias disponívels para testar o conhecimento antes de fazer a prova.

Develop code that uses the built-in interfaces included in the java.util.function package, such as Function, Consumer, Supplier, UnaryOperator, Predicate, and Optional APIs, including the primitive and binary variations of the interfaces

Observe the changes in a directory by using the WatchService interface

Create and manage date- and time-based events by using LocalDate, LocalTime, LocalDateTime, Instant, Period, and Duration, including a combination of date and time in a single object

Alguns arquivos possuem exemplos do teste que não compilam. Ao tentar executar um arquivo pontual no IDEA ele começa a reclamar de todos os arquivos que não "funcionam".

Talvez adicionando todas as exceções e commitando no repositório isso evite que outros devs tenham que realizar o mesmo processo em suas máquinas para visualizar um resultado pontual de outra classe.

No Eclipse não acontece esse problema por compilar apenas o arquivo desejado (o main do arquivo).

Describe the Stream interface and pipelines; create a stream by using the Arrays.stream() and IntStream.range() methods; identify the lambda operations that are lazy

Operate on file and directory paths by using the Paths class

Deixar o README do projeto o mais simples possível porque o GitHub não aceita includes do ASC. Sendo assim, para evitar de repetir conteúdo, seria mais fácil deixar o projeto bem básico. Isso vai facilitar a manutenção colocando todas as informações relevantes dentro to livro.

Use Lock, ReadWriteLock, and ReentrantLock classes in the java.util.concurrent.locks and java.util.concurrent.atomic packages to support lock-free thread-safe programming on single variables

Work with dates and times across time zones and manage changes resulting from daylight savings

Use the parallel Fork/Join Framework

Develop code that iterates a collection, filters a collection, and sorts a collection by using lambda expressions

Find a file by using the PathMatcher interface, and use Java SE 8 I/O improvements, including Files.find(), Files.walk(), and lines() methods

• Missing package and import statements: If sample code do not include package or import statements, and the question does not explicitly refer to these missing statements, then assume that all sample code is in the same package, or import statements exist to support them.
• No file or directory path names for classes: If a question does not state the file names or directory locations of classes, then assume one of the following, whichever will enable the code to compile and run:
• All classes are in one file
• Each class is contained in a separate file, and all files are in one directory
• Unintended line breaks: Sample code might have unintended line breaks. If you see a line of code that looks like it has wrapped, and this creates a situation where the wrapping is significant (for example, a quoted String literal has wrapped), assume that the wrapping is an extension of the same line, and the line does not contain a hard carriage return that would cause a compilation failure.
• Code fragments: A code fragment is a small section of source code that is presented without its context. Assume that all necessary supporting code exists and that the supporting environment fully supports the correct compilation and execution of the code shown and its omitted environment.
• Descriptive comments: Take descriptive comments, such as "setter and getters go here," at face value. Assume that correct code exists, compiles, and runs successfully to create the described effect.

Depois de gerar uma nova versão e realizar o rebase do conteúdo do master com o develop, um novo build é acionado no travis. Isso não é necessário acontecer.

Exemplo:
Merge pull request #45 from duke-certification/develop

Check, delete, copy, or move a file or directory by using the Files class

Language Enhancements: Develop code that handles multiple Exception types in a single catch block.

Utilizar travis-ci para realizar o deploy dos formatos do livro e tudo que estiver ligado no processo de entrega do livro para conseguir focar apenas no conteúdo.

Describe a lambda expression; refactor the code that uses an anonymous inner class to use a lambda expression; describe type inference and target typing

Problema identificado ao gerar o PDF. Ao retirar a sessão 2 o PDF fica correto ao juntar a sessão 1 e 3. Ir mais a fundo para idenfiticar se existe algum problema de syntax na sessão 2.

Identificado ao fazer a issue #3
