Summary

This book is one volume in China Machine Press's "Programmer Interview and Written Exam Series," aimed at readers preparing for campus and experienced-hire recruitment for Java positions at IT companies. The book is divided into two parts. Part One covers interview and written exam experience and techniques: first, interviewers from several well-known companies discuss hiring standards and views on career growth; then a group of job seekers from key universities who work at well-known companies recount real job-hunting experiences and lessons; next, the recruitment processes and assessment priorities of different types of employers—internet companies, network equipment providers, foreign companies, state-owned enterprises, research institutes, and startups—are analyzed one by one, along with practical advice on obtaining job information, writing resumes, online applications, interview etiquette, telephone interviews, group interviews, and signing contracts, as well as how to handle technical and non-technical written exams. Part Two tackles technical topics, organizing knowledge points by chapter: Java fundamentals (basic concepts, object-oriented technology, keywords, primitive types and operations, strings and arrays, exceptions, IO, the Java platform and memory management, containers, multithreading, JDBC), Java Web (Servlet and JSP, J2EE and EJB, common frameworks), database principles, networking and communication, operating systems, design patterns, and data structures and algorithms, plus a dedicated analysis of interview questions on massive data processing. The book is organized in question-and-answer form, with reference answers and related knowledge points for each question, making it easy to search by topic and focus on weak areas.

Editor's review

很多Java面试书只给你答案，这本书难得地把“答案之外”的东西也摆上了台面：一面是企业面试官眼里的合格标准，一面是刚走过校招的求职者踩过的坑，两相对照，读者能明白企业到底在挑什么样的人，而不只是背会几道题。它的篇章设计也符合备考节奏：上篇解决“怎么找、怎么投、怎么谈”，把互联网企业、外企、国企、研究所、创业公司的招聘流程逐一拆开讲，简历、网申、电话面试、集体面试、签约等环节都落到具体做法；下篇才进入技术硬功夫，从Java语法与面向对象，到容器、多线程、IO与JVM内存，再到Web、数据库、网络、操作系统、设计模式和算法，知识面覆盖得相当完整，并且按问答组织，哪一块薄弱就翻哪一块。海量数据处理专题是同类书中较少见的加分项，对准备大厂笔试的人尤其实用。需要提醒的是，本书成书于2014年，技术细节与招聘形态都带有那个时期的印记，作为知识框架和面试思路的底本仍然好用，但框架版本、并发工具等内容需结合更新的资料补充。

Who it's for

A good fit for

准备Java岗位校招、需要系统梳理笔试面试知识点的计算机相关专业学生
已工作一到三年、想跳槽到大厂的Java开发工程师
不熟悉国内IT企业招聘流程、需要了解各类型企业考查重点的转行者
希望从面试官视角理解用人标准、改进简历与表达方式的求职者

Not a good fit for

希望学习最新Java版本特性与主流框架实践的读者，本书内容停留在2014年前后
零基础、尚未掌握Java基本语法的初学者，直接刷题容易受挫
只想找算法竞赛类高难度题目的人，本书侧重企业常见考点而非竞赛训练

Reading tips

先通读上篇并用一两页纸写下自己的求职时间表与目标企业类型，再进入技术篇
技术篇按“自测—补漏—复述”三步走：先看题自答，再补知识点，最后合书讲给别人听
把容器、多线程、JVM内存、数据库与算法列为高优先级，这几块在笔试中出现频率最高
遇到框架与版本相关内容时，对照官方文档和较新的资料核对，不要照搬书中结论

FAQ

这本书和第二版有什么区别，该买哪一版？

初版由何昊、薛鹏、叶向阳编著，2014年出版；第二版更名《Java程序员面试笔试宝典（第2版）》，2021年由何昊、郭晶晶、薛鹏等编写，ISBN为9787111690382，内容按近三年考点重编，涵盖容器、多线程、IO、Java Web与数据库等。若目标是当下的校招，建议优先选第二版；若只想补基础概念，初版仍可参考。

书里的题目现在还有用吗？

Java语法、面向对象、集合与并发的基本原理、数据库与操作系统这些考点变化不大，仍然有效；但涉及具体框架版本、JVM参数默认值、Java新版本特性的内容可能已经过时，建议以官方文档为准进行核对。

没有项目经验，只看这本书能过面试吗？

不够。本书解决的是知识储备与答题表达，面试官同样看重项目经历与动手能力。建议边读边做一个小项目，把书中讲到的容器、多线程、数据库操作真正用一遍，面试时才有可讲的细节。

适合作为Java入门教材吗？

不适合。全书以问答和考点为单位组织，默认读者已具备Java基础。零基础读者可先用一本系统教程打底，再用本书做查漏补缺和面试准备。

海量数据处理那一章需要重点看吗？

如果投递的是互联网大厂的后端或数据相关岗位，值得细读，这类题在笔试中常以场景题形式出现；如果投递的是传统企业或研究所，可先跳过，把时间放在基础与数据库上。

About the author

何昊 Author

He Hao is an author about whom limited public information is available. What can be confirmed is that he wrote Blockchain Architecture Beauty: Blockchain Architecture Design Seen Through Bitcoin, Ethereum, and Hyperledger, a book catalogued under general computer science. Judging from its subject matter, the author focuses on the underlying architecture and design logic of blockchain, choosing Bitcoin, Ethereum, and Hyperledger—three representative systems—as entry points for comparative analysis, rather than staying at the level of concept popularization or a list of applications. This approach requires a certain overall grasp of distributed systems, consensus mechanisms, and ledger structures, and reflects a writing style oriented toward engineering perspectives and technical dissection. For readers who wish to understand blockchain design at the architectural level, the book offers a reading path that starts from actual systems. Because He Hao's education, professional background, and other works are not found in public sources, his personal history cannot be supplemented here; this introduction is limited to an objective account of the available work.
