Lambda: A Peek Under the Hood - Lecture 16

Explore the implementation details of lambda expressions in Java SE 8 through this in-depth conference talk. Dive into the technical aspects of closures and default methods, understanding why they were added to the language and how they differ from inner classes. Learn about the invokedynamic feature from Java SE 7 and its role in lambda implementation. Discover new bytecode tools like MethodHandle and various invocation modes. Examine the process of desugaring lambdas to methods, factories, and metafactories. Analyze performance costs, including linkage and capture costs, through practical examples. Gain insights into potential future VM support, serialization, and the broader implications for languages beyond Java. Enhance your understanding of Java's evolution and the powerful capabilities introduced by lambda expressions.
