Section 9 : Streams API Operations

• This section covers different Streams API operations that can be used in Streams to achieve an objective.
• Streams Operations such as :
  • map()
  • flatMap()
  • distinct()
  • count()
  • filter()
  • reducer()

• Terminal Operations such as :
  • joining()
  • counting()
  • mapping()
  • max(), min()
  • sum()
  • average()
  • groupingBy()
  • partitioningBy()

Section 12: Streams API – Parallel Processing

• This section covers how to perform the Parallel processing using Streams.
• How Parallel Programming makes use of the processors in your machine to perform concurrency operations?
• How Parallel Programming works internally ?
• How to check the performance between the sequential and parallel programming ?
• Scenarios when not to use parallel programming.

Section 12: Optional

• This section covers What is Optional and the benefits of Optional.
• How Optional can help you avoid Null Pointer exception.
• Exploring the different operations that are part of Optional such as :
  • empty()
  • ofNullable()
  • of()
  • orElse()
  • orElseGet()
  • orElseThrow()
  • isPresent()
  • ifPresent()
  • map()

  • filter()

Section 12: New Date/Time Libraries

• This section covers new Date/Time Libraries such as LocalDate, LocalTime, LocalDateTime.
• How to create/edit the LocalDate,LocalTime and LocalDateTime instances using different approaches.
• How to find the difference between the LocalDate, LocalTime and LocalDateTime using Period, Duration.
• How to represent the time in the Machine Readable Format using Instant.
• How to use the TimeZone using the ZonedDateTime.
• How to Format the Date using the DateTimeFormatter.

By the end of this course you will have a complete understanding of all the Java 8 features and implement it in real Java projects.
