Exam Topics

Working with Java data types
  • Use primitives and wrapper classes, including, operators, parentheses, type promotion and casting
  • Handle text using String and StringBuilder classes
  • Use local variable type inference, including as lambda parameters
Java Object-Oriented Approach
  • Declare and instantiate Java objects including nested class objects, and explain objects' lifecycles (including creation, dereferencing by reassignment, and garbage collection)
  • Define and use fields and methods, including instance, static and overloaded methods
  • Initialize objects and their members using instance and static initialiser statements and constructors
  • Understand variable scopes, apply encapsulation and make objects immutable
  • Create and use subclasses and superclasses, including abstract classes
  • Utilize polymorphism and casting to call methods, differentiate object type versus reference type
  • Create and use interfaces, identify functional interfaces, and utilize private, static, and default methods
  • Create and use enumerations
Working with Arrays and Collections
  • Use generics, including wildcards
  • Use a Java array and List, Set, Map and Deque collections, including convenience methods
  • Sort collections and arrays using Comparator and Comparable interfaces
Java Platform Module System
  • Deploy and execute modular applications, including automatic modules
  • Declare, use, and expose modules, including the use of services
Java I/O API
  • Read and write console and file data using I/O Streams
  • Implement serialization and deserialization techniques on Java objects
  • Handle file system objects using java.nio.file API
Database Applications with JDBC
  • Connect to and perform database SQL operations, process query results using JDBC API
Annotations
  • Create, apply, and process annotations
Controlling Program Flow
  • Create and use loops, if/else, and switch statements
Exception Handling
  • Handle exceptions using try/catch/finally clauses, try-with-resource, and multi-catch statements
  • Create and use custom exceptions
Working with Streams and Lambda expressions
  • Implement functional interfaces using lambda expressions, including interfaces from the java.util.function package
  • Use Java Streams to filter, transform and process data
  • Perform decomposition and reduction, including grouping and partitioning on sequential and parallel streams
Concurrency
  • Create worker threads using Runnable and Callable, and manage concurrency using an ExecutorService and java.util.concurrent API
  • Develop thread-safe code, using different locking mechanisms and java.util.concurrent API
Secure Coding in Java SE Application
  • Develop code that mitigates security threats such as denial of service, code injection, input validation and ensure data integrity
  • Secure resource access including filesystems, manage policies and execute privileged code
Localization
  • Implement Localization using Locale, resource bundles, and Java APIs to parse and format messages, dates, and numbers
