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
