Transforming Your Code to Java 8
summary
Shows concrete Java 8 rewrites: replace indexed Thread creation with lambdas and IntStream.range to remove mutable i and final hacks, find 100 primes with an infinite Stream.iterate plus filter map limit collect to List, list directory names via streams and Collectors.joining, sort with Comparator.comparing instead of mutating input, and replace finalize with try-with-resources and an execute‑around pattern using Consumer. Each refactor compiles and runs, cuts ceremony, and keeps behavior identical while improving clarity.
