| Java Fundamentals | - Create and use final classes - Create and use inner, nested and anonymous classes - Create and use enumerations |
| Java Interfaces | - Create and use interfaces with default methods - Create and use interfaces with private methods |
| Functional Interface and Lambda Expressions | - Define and write functional interfaces - Create and use lambda expressions including statement lambdas, local-variable for lambda parameters |
| Built-in Functional Interfaces | - Use interfaces from the java.util.function package - Use core functional interfaces including Predicate, Consumer, Function and Supplier - Use primitive and binary variations of base interfaces of java.util.function package |
| Migration to a Modular Application | - Migrate the application developed using a Java version prior to SE 9 to SE 11 including top-down and bottom-up migration, splitting a Java SE 8 application into modules for migration - Use jdeps to determine dependencies and identify ways to address the cyclic dependencies |
| Concurrency | - Create worker threads using Runnable, Callable and use an ExecutorService to concurrently execute tasks - Use java.util.concurrent collections and classes including CyclicBarrier and CopyOnWriteArrayList - Write thread-safe code - Identify threading problems such as deadlocks and livelocks |
| I/O (Fundamentals and NIO2) | - Read data from and write console and file data using I/O Streams - Use I/O Streams to read and write files - Read and write objects by using serialization - Use the Path interface to operate on file and directory paths - Use the Files class to check, delete, copy or move a file or directory - Use the Stream API with Files |
| Database Applications with JDBC | - Connect to databases using JDBC URLs and DriverManager - Use PreparedStatement to perform CRUD operations - Use PreparedStatement and CallableStatement APIs to perform database operations |
| Annotations | - Describe the purpose of annotations and typical usage patterns - Apply annotations to classes and methods - Describe commonly used annotations in the JDK - Declare custom annotations |
| Exception Handling and Assertions | - Use the try-with-resources construct - Create and use custom exception classes - Test invariants by using assertions |
| Generics and Collections | - Use wrapper classes, autoboxing and autounboxing - Create and use generic classes, methods with diamond notation and wildcards - Describe the Collections Framework and use key collection interfaces - Use Comparator and Comparable interfaces - Create and use convenience methods for collections |
| Java Stream API | - Describe the Stream interface and pipelines - Use lambda expressions and method references |
| Lambda Operations on Streams | - Extract stream data using map, peek and flatMap methods - Search stream data using search findFirst, findAny, anyMatch, allMatch and noneMatch methods - Use the Optional class - Perform calculations using count, max, min, average and sum stream operations - Sort a collection using lambda expressions - Use Collectors with streams, including the groupingBy and partitioningBy operations |
| Services in a Modular Application | - Describe the components of Services including directives - Design a service type, load services using ServiceLoader, check for dependencies of the services including consumer and provider modules |
| Parallel Streams | - Develop code that uses parallel streams - Implement decomposition and reduction with streams |
| Secure Coding in Java SE Application | - Prevent Denial of Service in Java applications - Secure confidential information in Java application - Implement Data integrity guidelines- injections and inclusion and input validation - Prevent external attack of the code by limiting Accessibility and Extensibility, properly handling input validation, and mutability - Securely constructing sensitive objects - Secure Serialization and Deserialization |
| Localization | - Use the Locale class - Use resource bundles - Format messages, dates, and numbers with Java |
