1. **Analyze the Request:** * **Role:** Course editor on GetFromCode, target audience: developers needing source code, tutorials, and practical engineering references. * **Tone:** Engineering-oriented, structural, reuse-focused, no marketing fluff. * **Perspective:** Tech stack, project structure, reusable modules, learning path. * **Hard Requirements:** * Only write an introduction/guide, no full directory listing, no zip/mp4 filenames. * No cliches: "Course recommendation", "Skill harvest", "Employment development", "Industry expert carefully crafted", "Complete learning path from beginner to advanced". * No claiming to be AI, no mentioning other site names. * Simplified Chinese. * Output HTML fragments using `
`, `
`, `
`, `
`, no ``/``. * Word count: 500-1000 Chinese characters (excluding punctuation and English). Strictly enforced. * 2-3 subheadings, each section explains clearly, no too many sub-sections. * Must include: Problem solved, suitable foundation, suggested modules to watch first, independent capabilities after learning, how materials support practice. * Must not copy the exact course title verbatim (but can refer to the topic). Wait, the prompt says "不要原样重复完整课程标题" (Don't verbatim repeat the full course title). I should refer to it as "线程八大核心+Java并发底层原理精讲" or just describe the topic. * Title in prompt has `|`, only keep the IT/programming part: "线程八大核心+Java并发底层原理精讲". * Material线索 only for understanding the topic, no copying filenames/extensions. 2. **Deconstruct the Course Title & Topic:** * Title: 线程八大核心+Java并发底层原理精讲 * Topic: Java Concurrency, Thread lifecycle, synchronization, volatile, ExecutorService, thread pools, etc. * Category: Testing & Operations (implies backend engineering, high-concurrency scenarios, system stability). 3. **Drafting - Section by Section (aiming for 500-1000 Chinese characters):** * *Subheading 1: 解决什么问题* * Focus: Why do developers struggle with Java concurrency? Memory visibility, thread lifecycle, deadlocks, performance bottlenecks. This course provides the engineering depth to solve these. * *Subheading 2: 适合什么基础与建议先看哪几块* * Focus: Requires solid Java basics (JVM, OOP). Suggest watching the core threads lifecycle and synchronization modules first, then dive into JUC底层. * *Subheading 3: 学完能独立做什么与资料配合练习* * Focus: Can independently design thread pools, fix concurrency bugs, optimize high-concurrency code. Materials include code snippets and project structures for hands-on practice. 4. **Drafting the Content (Iterative refinement for tone and word count):**
