## Parent Issue Part of #4408 — Remove Scala from StreamPark. ## Implementation Track Delivered in PR #4418 on branch `feature/remove-scala`. ## Scope Design and implement `FlinkStreamingJob` abstract base class in `org.apache.streampark.flink.core.java` package. Preserve lifecycle execution order: `main` → `init` → `ready` → `handle` → `execute` → `destroy`. Use Java DataStream API exclusively (Flink 1.17–1.20). ## Estimated Files ~1 new Java file; replaces `FlinkStreaming.scala` ## Dependencies - Depends on #4417 (JDK 11 baseline) ## Acceptance Criteria - [ ] `FlinkStreamingJob` compiles and lifecycle order matches Scala trait\n- [ ] `handle()` is abstract; `ready()`, `destroy()`, `configure()` have empty defaults\n- [ ] Migration note added to Javadoc --- _Sub-issue 0.1 of Scala removal epic (#4408)._ -- This is an automated message from the Apache Git Service.
