Oracle 1Z0-813 Syllabus Topics:

Language Enhancements - Develop code that 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 in a single catch block
- Use static and default methods of an interface including inheritance rules for a default method
Localization - Describe the advantages of localizing an application and developing code that defines, reads, and sets the locale with a Locale object
- Build a resource bundle for a locale and call a resource bundle from an application
- 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
- Format dates, numbers, and currency values for localization with the NumberFormat and DateFormat classes, including number and date format patterns
- Work with dates and times across time zones and manage changes resulting from daylight savings
Lambda - Define and write functional interfaces and describe the interfaces of the java.util.function package
- Describe a lambda expression; refactor the code that uses an anonymous inner class to use a lambda expression; describe type inference and target typing
- 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
- Develop code that uses a method reference, including refactoring a lambda expression to a method reference
Java Streams - 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
- Develop code that uses parallel streams, including decomposition operation and reduction operation in streams
Concurrency - Use classes from the java.util.concurrent package including CyclicBarrier and CopyOnWriteArrayList with a focus on the advantages over and differences from 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
Java File I/O (NIO.2) - Operate on file and directory paths by using the Paths class
- Check, delete, copy, or move a file or directory by using the Files class
- Recursively access a directory tree by using the DirectoryStream and FileVisitor interfaces
- Find a file by using the PathMatcher interface, and use Java SE 8 I/O improvements, including Files.find(), Files.walk(), and lines() methods
- Observe the changes in a directory by using the WatchService interface
Java Collections - Develop code that uses diamond with generic declarations
- Develop code that iterates a collection, filters a collection, and sorts a collection by using lambda expressions
- Search for data by using methods, such as findFirst(), findAny(), anyMatch(), allMatch(), and noneMatch()
- 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 Java SE 8 collection improvements, including the Collection.removeIf(), List.replaceAll(), Map.computeIfAbsent(), and Map.computeIfPresent() methods
- Develop  code that uses the merge(), flatMap(), and map() methods on Java Streams
Assume the following: - 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.
