Chapter 1 Course Guidance
Internet job under the winter, the current first-line interview Internet giant Java engineer jobs pay more attention to examine the candidates Java core libraries and source code usage, JVM bottom, GC, database, redis technology. This chapter describes the learning objectives of the course, curriculum, curriculum harvest. Chapter 2 core computer network interviews in this section is collected from a large number of first-tier Internet giant written interview questions as a basis, the statistics often test of knowledge: seven network architectures, TCP / IP protocol, TCP connection, tcp / udp difference, http and https, socket principle, the use of the way to explain the progressive layers, there are principles have practical operation demonstration, so that we more deeply understand and master the network layer related core test sites. ... Chapter 3 database This chapter explains relational database to mainstream Mysql, for example, particularly in LeeCode exam basis, starting from the first database architecture, progressive-depth analysis of the optimization of the index, and then through the code shows Sql optimization, and finally to explain the depth of the senior lock database interview extra points and raise points, followed by the ACID properties go further extended to the database through the lock, and there is a problem of concurrency scenarios that demonstrate their solutions. ... Chapter 4 Redis this section to non-relational database / cache database Redis core, introduces common data types and their use redis, and then through a typical interview scenarios, to talk further distributed lock, asynchronous queue, and internal strength demonstration code, and finally talk about persistence technology redis enhance students cultivation. Chapter Linux 5 Linux work most frequently used commands introduced, such as the find, grep, awk, sed, etc. Chapter 6 Java underlying knowledge: JVM
This section first independence from the Java platform, leads JVM paying this interview will test sites, and then analyze the JVM class loading process, and class loader, and deep into the underlying mechanisms of class loading - parents delegate, and finally advanced to the JVM system memory model structure, the depth of analysis memory model associated with the test sites. Offer to provide a strong guarantee for high-paying students. ...
Chapter 7 Java underlying knowledge: GC relevant
in this section focus on Java's garbage collection, full of dry goods. As a Java programmer knows that high-performance Java language, in fact, depend on reliable GC mechanism. This chapter will revolve around the principle that the algorithm GC-related, so that students understand the GC various algorithms and how to perform configuration. Chapter 8 Java multithreading and concurrency in this section are commonly used around the work, compulsory interview threads and concurrency knowledge, theory and practical operation complement each other. Introduces processes and threads, and then explain the state of the thread, then cut locks talk about hapens-before and the like, and finally talk about the Thread class, thread pool and its operating mechanism. Let your targeted at multithreading and concurrent interview, even more powerful. ... Chapter 9 Java multithreading and concurrency - the principles of this section on the basis of the previous chapter, pay more attention to the underlying principles of analysis and practical operation, are more difficult to answer in an interview, reflecting a chapter of personal ability and knowledge. If, after the students master the understanding, is reflected in the resume, highlight this part of the interview will give you considerably. Chapter 10 Java class libraries and techniques used in this section explain some comprehensive JAVA-related interview test sites, from libraries to exception handling, to explain skills, such as: HashMap, HashTable red-black tree and ConcurrentHashMap, Hash conflict, Queue, IO / NIO, etc. Chapter 11 Java framework -Spring
This chapter focuses framework interview to the mainstream framework spring, for example, to explain the IOC thought, decoupling, AOP uses, things 5 transaction isolation level, seven transaction propagation behavior, the final realization of a simple spring through hands-on code. The principle and achieve a combination of written test and interview conducted blessing, enhance programming capabilities. Chapter 12 Lessons Learned and Prospects Review of core curriculum content.
