Map, Flatmap, and Reduce Are Your New Best Friends
 
01:01:16
Higher-order functions such as map(), flatmap(), filter(), and reduce() have their origins in mathematics and ancient functional programming languages such as Lisp. But today they are well on their way to becoming an essential part of every Java and Scala developer’s toolbox. In this session, you will learn how these and other higher-order functions enable you to write simple, expressive, and concise code that solves problems in a diverse set of domains. The presentation describes how you can use them to process collections in Java and Scala. You will learn how functional Futures and Reactive Extensions (Rx) observables simplify concurrent code and how to write big data applications in a functional style with libraries such as Scalding.

Google still free to use Java in Android, Oracle to appeal decision
 
02:06
On Thursday Google dodged a bullet that could have cost the company 9 Billion dollars. Here's the play by play. Google uses the open source platform Java in its Android operating system. Oracle, which owns the copyright for Java, sued Google for copyright infringement. Thursday a federal court ruling in favor of Google stated that the company’s use of 37 of Java’s API is protected by Fair use. This isn’t merely a win for google, it a win for everyone that uses apps. If this judgment had gone the other way, app developers who depend on the ability to freely use API’s, would have been hamstrung by an assortment of legal roadblocks.

Oracle Java SE 8 (JDK 8) Lambdas & Streams MOOC Overview-Starts Dec. 2, 2016
 
02:31
Enrollment here: https://apexapps.oracle.com/pls/apex/f?p=44785:145:0::::P145_EVENT_ID,P145_PREV_PAGE:5067,143 Java SE 8 (JDK 8) Introduced a fundamentally new way of programming in Java with the introduction of Lambda expressions. Lambda provides a simple way to pass functionality as an argument to another method, such as what action should be taken when someone clicks a button, or how to sort a set of names. Lambda expressions enable you to do this, to treat functionality as method argument, or code as data. You may have heard about Lambda, and are curious what impact it will have on you as a Java developer. This 3 week course is designed to answer your questions and more. * Have you ever wondered what lambda expressions are in Java? * Have you ever wanted to write parallel code in Java without worrying about threads and locking? * Have you ever wanted to process collections of data without using loops? * Have you ever wanted to do functional programming in Java? All of these questions will be answered in this practical hands-on MOOC. ================================= For more information, see http://www.oracle.com/goto/oll Copyright © 2015 Oracle and/or its affiliates.

Programming with Lambda Expressions in Java
 
58:51
Now that Java is supporting lambda expressions, it’s time to hone our skills to make use of them. Lambda expressions can help create concise code, but it takes more than learning the syntax to put them to good use. In this session, you will learn the idiomatic use of lambda expressions, explore the ways you can use them to do common tasks, and look into libraries and APIs that make use of them in Java.

Java Interview Series - 2 | Difference between Hashmap and HashTable | Team MAST
 
03:04
You will learn 5 differences between Hashmap and HashTable. HashMap and Hashtable both are used to store data in key and value form. Both are using hashing technique to store unique keys. This question is generally asked in java intereview to check whether candidate understand correct usage of collection classes and has knowledge of alternative solutions. Major questionis, When to use HashMap and Hashtable? 1. Single Threaded Application HashMap should be preferred over Hashtable for the non-threaded applications. In simple words , use HashMap in unsynchronized or single threaded applications . 2. Multi Threaded Application We should avoid using Hashtable, as the class is now obsolete in latest Jdk 1.8 . Oracle has provided a better replacement of Hashtable named ConcurrentHashMap. For multithreaded application prefer ConcurrentHashMap instead of Hashtable.

Optional - The Mother of All Bikesheds by Stuart Marks
 
58:43
Subscribe to Devoxx on YouTube @ https://bit.ly/devoxx-youtube Like Devoxx on Facebook @ https://www.facebook.com/devoxxcom Follow Devoxx on Twitter @ https://twitter.com/devoxx The Optional class was introduced in Java 8 in order to solve a narrow but frequently occurring problem: what to return if you have nothing to return. It is a single class with less than 20 methods, but it turns out to have been one of the most controversial and most misunderstood APIs, having generated several "centithreads" of discussion on OpenJDK mailing lists. Indeed, Brian Goetz (Oracle's Java Language and Libraries Architect) has mentioned that one aspect of Optional was his biggest mistake in Java 8. Optional is also one of the more widely misused APIs. A brief survey of OpenJDK code revealed several embarrassing examples of Optional usage, and expert Java programmers have admitted to not making the most of this API. This session covers the history and rationale of Optional, provides recommendations and examples of proper and effective usage, shows several antipatterns and code smells and how to fix them, and finally describes some current and proposed work on Optional for Java 9. Stuart Marks is a Principal Member of Technical Staff in the Java Platform Group at Oracle. He is currently working on a variety of JDK core libraries projects, including Collections, Lambda, and Streams, as well as improving test quality and performance. As his alter ego "Dr Deprecator" he also works on the Java SE deprecation mechanism. He has previously worked on JavaFX and Java ME at Sun Microsystems. He has over twenty years of software platform product development experience in the areas of window systems, interactive graphics, and mobile and embedded systems. Stuart holds a Master's degree in Computer Science and a Bachelor's degree in Electrical Engineering from Stanford University. [VXM-7030]

This session presents a survey of the principal families (list, set, map, and queue) of the Java collections ecosystem and their major and minor members. It examines differences between the collection families and family members, with special attention to the preferred environment of each collection species. Exotic, rarely seen creatures such as SynchronousQueue and ConcurrentSkipListMap are also included. The discussion of the recent evolutionary advances to collections and insights from the fossil record will inform and inspire all those who delight in these most ubiquitous of Java classes.

But there are a few applications, including Linux, Oracle, MySQL, and Java that delight in confounding. Maybe it's a perception of required hyper-specialization to master them. Maybe it's many version permutations. Or maybe it's just good old FUD. This session will help lessen your concerns.

A Few Hidden Treasures in Java 8

Sure, Java 8 has lambdas and streams, but the JDK has gone through a significant makeover to make good use of lambdas and streams. Furthermore, some of the new functional interfaces have far more than abstract methods. This presentation goes beyond lambdas and streams and takes a look at some of the fun-filled, useful elements of the JDK that will help us make better use of lambdas and streams.
