Renaming across modules in NetBeans is risky – manual replace can break code. NetBeans' Rename (Shift+F6) uses AST analysis and a preview window to update all references safely. This post walks through a concrete example, highlights limits, and shows how to verify the change.
Stop fighting 'jar hell' and version drift. Learn how to use Maven's <dependencyManagement> and the BOM pattern to centralize version control in multi-module projects.
Learn how to add a Dropwizard HealthCheck to verify service liveness, see a full code example, and understand the limits and common pitfalls.
When integrating Codecov into a Java CI workflow, you can choose Cobertura XML or lcov plain‑text coverage reports. This guide weighs the constraints, trade‑offs, and shows how to generate and validate each format with JaCoCo and the Codecov CLI.
Java records reduce boilerplate for immutable data carriers, but their validation does not run during deserialization, requiring explicit trust boundaries and operational checks.
Offset pagination gets slower as you go deeper. Learn how DTO projections and keyset pagination keep Hibernate queries fast on large tables.
Stop duplicating test logic. Learn how to use JUnit 5 @ParameterizedTest, @ValueSource, and @MethodSource to decouple test data from logic and reduce boilerplate.
HTTP/1.1 forces browsers to open multiple TCP connections and suffer head-of-line blocking. Tomcat's NIO2 connector can multiplex HTTP/2 streams over one TLS connection—if you configure it correctly.
How Hibernate's second-level cache with Ehcache serves repeated entity reads from memory, plus consistency and heap trade-offs.
