Java developers often close resources manually using try-catch-finally, but since JDK 7 the try‑with‑resources construct automates this process; this article explains the traditional pattern, demonstrates the new syntax, shows how to implement custom Closeable classes, and reveals the compiler‑generated bytecode that preserves original exceptions via addSuppressed.
