Lambda Expressions in Java - Performance and Advanced Applications
Explore the world of lambda expressions in Java through this 44-minute presentation. Begin with a review of JDK 8 lambda expressions before delving into their performance implications, focusing on the use of invokedynamic instead of simple syntactic sugar for anonymous inner classes. Trace the 80-year history of lambda expressions back to Alonso Church's lambda calculus. Discover how a single new functional interface can theoretically solve any problem using only lambda expressions. Prepare for a mind-bending journey through topics including lambda expression syntax, method references, implementation differences, Church numerals, and solving basic arithmetic problems using lambdas. Challenge your understanding of Java programming and embrace a new perspective on functional programming concepts.
