  • Handle text using String and StringBuilder classes
  • Use local variable type inference, including as lambda parameters

2.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

3.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

4.Java Platform Module System

  • Deploy and execute modular applications, including automatic modules
  • Declare, use, and expose modules, including the use of services

5.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

6.Database Applications with JDBC

  • Connect to and perform database SQL operations, process query results using JDBC API

7.Annotations

  • Create, apply, and process annotations

8.Controlling Program Flow

  • Create and use loops, if/else, and switch statements

9.Exception Handling

  • Handle exceptions using try/catch/finally clauses, try-with-resource, and multi-catch statements
  • Create and use custom exceptions

10.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

11.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

12.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

13.Localization
