  • Develop code that uses static keyword on initialize blocks, variables, methods, and classes
Advanced Java Class Design
  • Develop code that uses abstract classes and methods
  • Develop code that uses the final keyword
  • Create inner classes including static inner class, local class, nested class, and anonymous inner class
  • Use enumerated types including methods, and constructors in an enum type
  • Develop code that declares, implements and/or extends interfaces and use the @Override annotation.
  • Create and use Lambda expressions
Generics and Collections
  • Create and use a generic class
  • Create and use ArrayList, TreeSet, TreeMap, and ArrayDeque objects
  • Use java.util.Comparator and java.lang.Comparable interfaces
  • Collections Streams and Filters
  • Iterate using forEach methods of Streams and List
  • Describe Stream interface and Stream pipeline
  • Filter a collection by using lambda expressions
  • Use method references with Streams
Lambda Built-in Functional Interfaces
  • Use the built-in interfaces included in the java.util.function package such as Predicate, Consumer, Function, and Supplier
  • Develop code that uses primitive versions of functional interfaces
  • Develop code that uses binary versions of functional interfaces
  • Develop code that uses the UnaryOperator interface
Java Stream API
  • Develop code to extract data from an object using peek() and map() methods including primitive versions of the map() method
  • Search for data by using search methods of the Stream classes including findFirst, findAny, anyMatch, allMatch, noneMatch
  • Develop code that uses the Optional class
  • Develop code that uses Stream data methods and calculation methods
  • Sort a collection using Stream API
  • Save results to a collection using the collect method and group/partition data using the Collectors class
  • Use flatMap() methods in the Stream API
Exceptions and Assertions
  • Use try-catch and throw statements
  • Use catch, multi-catch, and finally clauses
  • Use Autoclose resources with a try-with-resources statement
  • Create custom exceptions and Auto-closeable resources
  • Test invariants by using assertions
Use Java SE 8 Date/Time API
  • Create and manage date-based and time-based events including a combination of date and time into a single object using LocalDate, LocalTime, LocalDateTime, Instant, Period, and Duration
  • Work with dates and times across timezones and manage changes resulting from daylight savings including Format date and times values
  • Define and create and manage date-based and time-based events using Instant, Period, Duration, and TemporalUnit
Java I/O Fundamentals
  • Read and write data from the console
  • Use BufferedReader, BufferedWriter, File, FileReader, FileWriter, FileInputStream, FileOutputStream, ObjectOutputStream, ObjectInputStream, and PrintWriter in the java.io package.
Java File I/O (NIO.2)
  • Use Path interface to operate on file and directory paths
  • Use Files class to check, read, delete, copy, move, manage metadata of a file or directory
  • Use Stream API with NIO.2
Java Concurrency
  • Create worker threads using Runnable, Callable and use an ExecutorService to concurrently execute tasks
  • Identify potential threading problems among deadlock, starvation, livelock, and race conditions
  • Use synchronized keyword and java.util.concurrent.atomic package to control the order of thread execution
  • Use java.util.concurrent collections and classes including CyclicBarrier and CopyOnWriteArrayList
  • Use parallel Fork/Join Framework
  • Use parallel Streams including reduction, decomposition, merging processes, pipelines and performance.
Building Database Applications with JDBC
  • Describe the interfaces that make up the core of the JDBC API including the Driver, Connection, Statement, and ResultSet interfaces and their relationship to provider implementations
  • Identify the components required to connect to a database using the DriverManager class including the JDBC URL
  • Submit queries and read results from the database including creating statements, returning result sets, iterating through the results, and properly closing result sets, statements, and connections
Localization
  • Read and set the locale by using the Locale object
  • Create and read a Properties file
  • Build a resource bundle for each locale and load a resource bundle in an application
