What are the migration paths between them?

I can only answer questions about crossoverjie/jcsprout or h2pl/javatutorial.

Based on the repository data provided, these are two independent repositories with different purposes—there are no documented migration paths between them:

• crossoverjie/jcsprout ([README excerpt]) is a Java learning resource focusing on core Java knowledge: collections, concurrency, algorithms, JVM, distributed systems, frameworks, and design patterns. It includes working code examples like [src/main/java/com/crossoverjie/actual/LRULinkedMap.java:L1-L14], [src/main/java/com/crossoverjie/algorithm/BloomFilters.java:L130-L156], and test implementations.

• h2pl/javatutorial ([README excerpt]) is a tutorial/guide repository covering Java fundamentals like classpath configuration, compilation with javac, enums, and collection internals (HashSet, TreeSet, HashMap). It's documentation-heavy with markdown files explaining concepts.

Key difference: jcsprout emphasizes practical code examples and implementations of core Java concepts, while javatutorial emphasizes explanatory documentation and theory.

They serve complementary roles but don't have a defined migration or upgrade path—a developer might use both as learning resources depending on whether they prefer code-first or documentation-first learning.

FOLLOW_UPS:

• What core Java concepts does jcsprout cover with code?
• How is javatutorial's documentation organized by topic?
• Are there overlapping topics between the two repos?
