• Develop code that declares, implements and/or extends interfaces and use the @Override annotation.
• Create and use Lambda expressions

• 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

• 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

• 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

• Use throw and throws statements 
• Develop code that handles multiple Exception types in a single catch block
• Develop code that uses try-with-resources statements (including using classes that implement the AutoCloseable interface)
• Create custom exceptions
• Test invariants by using assertions

• Read and write data from the console
• Use streams to read from and write to files by using classes in the java.io package (including BufferedReader, BufferedWriter, File, FileReader, FileWriter, DataReader, ObjectOutputStream, ObjectInputStream, and PrintWriter)

• 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 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.

Java File I/O (NIO2)

• 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

• 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)
• Use JDBC transactions (including disabling auto-commit mode, committing and rolling back transactions, and setting and rolling back to savepoints)
• Construct and use RowSet objects using the RowSetProvider class and the RowSetFactory interface
• Create and use PreparedStatement and CallableStatement objects
