Refactoring to Java 8

Explore the benefits of Java 8 in this 71-minute conference talk by Trisha Gee. Learn how to automatically refactor code to leverage Java 8 features, comparing performance and readability before and after. Discover the advantages of lambda expressions, stream operations, and new collection methods. Gain insights into safety checks, designing for lambdas, and optimizing various loop constructs. Analyze the readability and performance implications of different refactoring approaches, including Stream.forEach, Stream.collect, Stream.anyMatch, Stream.findFirst, and Collection.removeIf. Conclude with a summary of findings and a Q&A session to deepen your understanding of effective Java 8 refactoring techniques.

Why Java 8
Safety checks

Performance of Lambda expressions
Designing for Lambda expressions
Refactoring “for” loop to Stream.forEach
Readability and performance: Stream.forEach vs “for” loop
Refactoring “for” loop to Stream.collect
Readability and performance: Stream.collect vs “for” loop
Collapsing multiple operations
Readability and performance: multiple operations
Refactoring “for” loop to Stream.anyMatch
Readability and performance: “for” loop vs Stream.anyMatch
Refactoring “for” loop to Stream.findFirst
Readability and performance: “for” loop vs Stream.findFirst
Refactoring to Collection.removeIf
Readability and performance: Collection.removeIf
