1Z0-813 Exam Topics
1) Language Enhancements
* Develop code which uses String objects in the switch statement, binary literals, and numeric literals, including underscores in literals
* Develop code that uses try-with-resources statements, including using classes that implement the AutoCloseable interface
* Develop code that handles multiple Exception types within a catch block
* Use static and default methods of an interface including inheritance rules for any default method
2) Localization
* Describe some great benefits of localizing an application and developing code that defines, reads, and sets the locale which has a Locale object
* Build a resource bundle for any locale and call a resource bundle from a software
* Create and manage date- and time-based events by using LocalDate, LocalTime, LocalDateTime, Instant, Period, and Duration, including a blend of starting time and date in a object
* Format dates, numbers, and currency values for localization together with the NumberFormat and DateFormat classes, including number and date format patterns
* Work with times across time zones and manage changes due to daylight savings
3) Lambda
* Define and write functional interfaces and describe the interfaces of the java.util.function package
* Describe a lambda expression; refactor the code that utilizes an anonymous inner class to utilize a lambda expression; describe type inference and target typing
* Develop code which utilizes the built-in interfaces within the java.util.function package, such as Function, Consumer, Supplier, UnaryOperator, Predicate, and Optional APIs, like the primitive and binary variations from the interfaces
* Develop code that utilizes a technique reference, including refactoring a lambda expression to some method reference
4) Java Streams
* Describe the Stream interface and pipelines; produce a stream with the Arrays.stream() and IntStream.range() methods; know the lambda operations which can be lazy
* Develop code which uses parallel streams, including decomposition operation and reduction operation in streams
5) Concurrency
* Use classes from your java.util.concurrent package including CyclicBarrier and CopyOnWriteArrayList with a pinpoint the advantages over and differences in the traditional java.util collections
* 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
* Use Executor, ExecutorService, Executors, Callable, and Future to execute tasks using thread pools
* Use the parallel Fork/Join Framework
6) Java File I/O (NIO.2)
* Operate on record and directory paths utilizing the Paths class
* Check, delete, copy, or move a file or directory using the Files class
* Recursively access a directory tree by using the DirectoryStream and FileVisitor interfaces
* Find folders utilizing the PathMatcher interface, and employ Java SE 8 I/O improvements, including Files.find(), Files.walk(), and lines() methods
* Observe modifications within a directory by using the WatchService interface
7) Java Collections
* Develop code which uses diamond with generic declarations
* Develop code that iterates a group, filters a group, and sorts an assortment through the use of lambda expressions
* Search for data by utilizing methods, for example findFirst(), findAny(), anyMatch(), allMatch(), and noneMatch()
* Perform calculations on Java Streams by making use of count, max, min, average, and sum methods and save results in a collection by using the collect method and Collector class, including the averagingDouble, groupingBy, joining, partitioningBy methods
* Develop code which uses Java SE 8 collection improvements, such as the Collection.removeIf(), List.replaceAll(), Map.computeIfAbsent(), and Map.computeIfPresent() methods
* Develop code that utilizes the merge(), flatMap(), and map() methods on Java Streams
8) Assume the following:
* Missing package and import statements
* No file or directory path names for classes
* Unintended line breaks
* Code fragments
* Descriptive comments
