这本使JAVA里面最重要的一本书，是我开始JAVA之旅的第一本书，希望大家能够好好研读一下，可以学到很多的东西，这本书所涵盖的内容比其他的要多地多，即包括基础知识，又包括高级的应用，不论你是自己编程还是做企业级的开发系统，我想这本书可以给你足够的参考。我那时看得是...
评分《java核心技术(卷1)》书评 最近花了一个多星期的时间看了《Java核心技术》卷一，感觉这本书是一本介绍java内容比较全面的一本书，几乎所有Java的知识点都有涉及，而且讲解的也很详细，对java的初学者来说是一本很好的入门书籍。该书对java中jdk的下载和安装部署都进行了详细的...
评分 评分断断续续快看完第九版第一卷英文版。刚开始时候，感觉这本书很贴近实际，开门见山便亮出正统完整的类似helloworld的例子，以及简单GUI的例子。在简洁地介绍java开发环境后，详细介绍一个完整的java程序涉及到的元素，充满了实用气息。 然而随着深入章节，到了第6章，以及第9章...
评分《Java核心技术卷一》是唯一可以和《[Java编程思想]》媲美的一本 Java 入门书。单从技术的角度来看，前者更好一些。但上升到思想层面嘛，自然后者更好，两者的偏重点不同。 思想不会变，所以《Java编程思想》还停留在第 4 版（2007 年）；而技术是要更新迭代的，所以《Java核心...

评分
这本书真是太给力了，尤其是对于我们这些想扎实掌握Java基础的开发者来说。我记得我刚开始接触编程的时候，Java那些复杂的概念总是让我望而却步，什么内存管理、JVM原理，听起来就像天书一样。但是翻开这本书，那种感觉完全不同了。它不是那种干巴巴地堆砌理论，而是用非常清晰、有条理的方式，把那些看似深奥的概念一层层剥开。特别是关于对象和类的那几章，作者的讲解简直是教科书级别的——逻辑严密，例子贴切，让你能真切地理解面向对象编程的核心思想。我尤其欣赏它在细节上的把握，比如在讲解基本数据类型的时候，不仅告诉你它们的用法，还会深入到它们在内存中是如何存储和表示的，这种底层视角的加持，让我在处理一些性能优化和并发问题时，思路一下子就清晰了很多。这本书读下来，感觉就像是请了一位经验丰富的大师手把手地带你入门，每一个知识点都夯实了，为后续学习更高级的框架和技术打下了无比坚实的基础。对于任何想要成为合格Java工程师的人来说，这绝对是案头必备的“圣经”。
评分坦率地讲，这本书的排版和组织结构是顶级的。我翻阅过不少计算机经典教材，很多内容组织得让人抓狂，章节之间逻辑跳跃，重点模糊不清。但《Java核心技术》的编排简直是艺术品级别的清晰。它将一个庞大的主题切分成若干个逻辑自洽的小单元，每一个单元都围绕一个核心概念展开，论证充分，层层递进。特别是当你需要快速回顾某个特定主题时，你会发现索引和章节标题设计得极其人性化，让你能迅速定位到需要的信息点，而不会被无关的内容干扰。此外，虽然内容专业，但作者的文字叙述却保持了一种冷静而克制的幽默感，这使得长时间阅读也不会产生强烈的疲劳感。它更像是一部严谨的学术著作，但同时又拥有百科全书般的易用性。我甚至把它当作工具书来用，每当遇到一个新的项目需求，我总能从这本书的某个角落找到与之相关的、最权威的解释。这种长久的使用价值，是很多“时髦”的技术书籍无法比拟的。
评分我个人感觉，这本书的深度和广度达到了一个非常完美的平衡点。很多技术书籍要么太偏重理论，读起来晦涩难懂，要么就是过于侧重实践，结果基础不牢地动摇。而这本《Java核心技术》则像一座精巧的桥梁，稳稳地连接了两端。它的内容覆盖面非常广，从基础的语法特性，到集合框架的内部实现，再到异常处理和泛型的精妙运用，几乎囊括了Java SE的核心领域。我印象最深的是它对Java I/O流的讲解，那部分内容我以前在其他资料里总是看得一知半解，但这本书里用图示和流程图的方式，把字节流和字符流的转换、缓冲区的效率提升等都讲得明明白白。更赞的是，作者似乎总能预料到读者可能会在哪里卡住，并在关键节点提供“陷阱”提示或者“最佳实践”建议。这种前瞻性的设计，让阅读过程充满了“原来如此”的顿悟感。如果你只是想快速扫一眼API文档，这本书可能不是最优选，但如果你想真正理解Java这门语言的“为什么”和“怎么做”，它绝对是无可替代的选择。
评分作为一名已经工作了几年，但总感觉自己知识体系存在“漏洞”的程序员，我不得不说，这本书帮我填补了太多过去的遗憾。很多时候，我们工作中用到的特性，比如Lambda表达式或者Stream API，我们只是停留在“能用”的层面，并没有深究其背后的设计哲学。这本书用非常优雅的笔触，重新审视了这些现代Java特性，让我看到了它们是如何提升代码的表达力和可读性的。举个例子，关于枚举类型的那章，它不仅仅是教你怎么定义一个enum，而是深入探讨了枚举如何实现接口、如何充当单例模式的完美替代品，这种深度挖掘让人叹服。每次我读完一个章节，都有一种“怪不得它会这样设计”的豁然开朗的感觉。这本书的语言风格是非常严谨且富有洞察力的，它不卖弄花哨的技巧，而是专注于构建一套坚不可摧的知识体系。对于追求卓越和想深入理解语言底层机制的开发者，这本书带来的价值是指数级的。
评分说句实在话，这本书的价值是时间沉淀下来的，它就像是Java语言发展历程中的一个里程碑式的记录。它没有过度关注那些转瞬即逝的框架或库的最新版本变化，而是聚焦于Java这门语言本身最核心、最稳定、最需要长期掌握的知识。这意味着你今天学习到的内容，五年后依然是判断一个Java工程师水平的基石。我尤其欣赏它对并发编程和多线程部分的处理，那部分内容简直是面试官的最爱，也是实际工程中 bug 的重灾区。作者没有使用过于复杂的术语来包装，而是通过具体的并发场景和同步机制（比如锁、volatile的正确用法）来教导读者如何写出健壮、无死锁的代码。读完后，你不再是简单地调用`Thread.start()`，而是真正理解了线程的生命周期和它们在JVM中是如何协作的。对于任何希望将自己的技能树从“能写代码”提升到“能设计和维护复杂系统”的工程师而言，这本书提供的深度和广度是无可替代的敲门砖。
评分相同一个项目，有人一个月，有人几个小时，这就是技术上的差距，熟练度，手熟尔--诚不我欺！本书按照引例和核心代码模式讲解概念和思想，这种写作模式很值得推荐。
评分主要完成了（1-7）章。跳过了GUI
