summary

Live coding shows Java 8 features with concrete examples: lambdas and streams for counting capital letters, using IntStream, mapToObj and method references to avoid boxing, and demonstrating lazy evaluation with peek and count. Optional usage replaces exceptions with Optional.ifPresent. Builds include OpenJDK on Raspberry Pi (reported ~18 minutes on a quad‑core $35 board) and a submitted OpenJDK 9 patch that later took months to accept. Also demonstrates a higher‑order function that returns a character chooser and the example runs successfully.
