Master the advanced/latest topics AND get Oracle OCP Certification (1Z0-829,1Z0-819,1Z0-809)
What you'll learn
Understand and apply functional programming techniques in Java i.e. lambda expressions (including method references) and Streams.
Obtain the knowledge of many advanced Java concepts such as Concurrency, Generics/Collections, Localization, JDBC and IO/NIO.2.
Master the new Java 9, 10 and 11 topics - local variable type inference, private interface methods, Annotations, Security and Modules.
Master the new Java 12, 13, 14, 15, 16 and 17 topics - sealed classes, records, switch expressions (including pattern matching) and text blocks.
Acquire the skills to pass the Oracle Java 8, 11 and 17 OCP exams (1Z0-809, 1Z0-819 and 1Z0-829).
Requirements
Ideally, have completed my "Complete Java 8 OCA (1Z0-808) Java Certification Course" here on Udemy as this course starts with lambda expressions.
Access to an IDE such as Netbeans, Eclipse or IntelliJ.
If preparing for any of the Java OCP certifications, ideally, you would use Enthuware in parallel (for excellent MCQ training).
Description
PDATE September 2023 - Java 21 added! Java 21 has now been officially released. Among its topics include the eagerly anticipated "Unnamed classes and instance main methods". In addition, other topics include sequenced collections; record patterns and pattern matching for switch.PDATE April 2023 - MAJOR NEWS - this course has been selected by Udemy for inclusion in their Udemy Business program. "Udemy Business is a curated (carefully chosen) selection of high-quality Udemy courses — like yours"demy email. "Only 3% of all courses are chosen for Udemy Business."demy email. Java has now 4 LTS (Long Term Support) releases: 8, 11, 17 and 21. This course covers them all : it addresses advanced Java 8 programming in addition to Java 11, 17 and 21.This course is a successor to my "Complete Java 8 OCA (1Z0-808) Java Certification Course", which covers Java fundamentals in great detail. As a result, this course starts with lambdas i.e. fundamentals such as classes, interfaces, operators and methods are not in this course. It is important to realise that while familiarity with Java is helpful, certification is certainly not a pre-requisite. This course starts with the advanced topics of Java 8 - lambdas, streams, collections, generics, concurrency etc.. There are assignments for lambdas, streams and collections.Java 11 is then covered - LVTI, private interface methods, annotations, security and modules. Modules are examined in detail (with examples). Java 17 is covered next - sealed classes, records, switch expressions, pattern matching and text blocks. A significant assignment covering all topics is included.Lastly, Java 21 is covered - unnamed classes and instance main methods, record patterns, pattern matching for switch and sequenced collections. An assignment covering all topics that builds on the Java 17 assignment, is included.All the code used throughout the course is available. Topics are presented with both general understanding and certification in mind i.e. the course caters for both. Regarding certification, Java 8 OCP (1Z0-809), Java 11 OCP (1Z0-819) and Java 17 OCP (1Z0-829) are targeted. This course would be a great training support in conjunction with the excellent MCQ Certification tool from Enthuware (as there are no MCQ's on this course).The theory of the topic is explained with lots of code examples used to reinforce the topic. The videos are annotated in detail to help the learner follow my explanations. Having access to the code is a great learning aid as you can get the code running and see what happens when you change it. In addition, the assignments/exercises are a great aid for learning.Topics include:Java 8 Advanced:Lambda ExpressionsStreamsGenericsCollectionsConcurrencyJDBCFile IONIO.2SerialisationLocalisationJava 11:private interface methodsLVTI (local variable type inference)AnnotationsSecurityModulesJava 17:Sealed classesRecordsswitch expressions and pattern matchingText blocksJava 21:Unnamed classes and instance main methodsRecord patternsPattern matching for switch Sequenced collectionsBy way of background, I am a PhD-qualified University lecturer since 2002. For over a decade, I have taught Java on a bespoke Masters on behalf of a highly regarded software company. I have recently co-authored a book called "Java Memory Management: a comprehensive guide to garbage collection and JVM tuning" with Maaike van Putten.I love teaching and this course has all my experience in explaining advanced concepts of Java. In addition, I have a strong attention to detail which lends itself perfectly to the Oracle Java Certification exams. I am delighted that Enthuware, in their explanations, have linked to my YouTube channel.
Who this course is for
Students/software professionals who want to take their Java beyond the fundamentals and understand advanced Java topics.
Students/software professionals wanting to master the new features in both Java 11 and Java 17.
Anyone preparing for the Java OCP Certification exams at either Java 8, 11 or 17 level.
