preface
Here are the skills you need to work for a first-tier Internet company like BAT. If you don’t know it well, consolidate it. If you don’t know it already, start studying it now.
1.Java language basics
Java Syntax Basics
Java classes and objects
Java inheritance and polymorphism
Advanced object-oriented features
Exception handling
multithreading
Input and output IO
Generics, Reflection, annotation;
2.Java Basic Class library
Java.lang package: Contains mainly language-specific classes. The java.lang package is automatically loaded by the interpreter without the need to display instructions.
Java.io package: Contains input/output related classes that provide support for reading and writing data to different input and output devices.
Java.util package: includes a number of classes with specific functionality, such as dates, vectors, hash tables, stacks, etc. The Date class supports time-related operations.
Java.net package: Contains classes related to network operations, such as TCP Scokets, URLS, and other tools.
Java.beans package: Defines an application programming interface (API), Java Beans is a neutral platform component structure for the Java application environment.
. , etc.
Java advanced features and class libraries
Java class loader
Java program run basic knowledge, Java compiled bytecode operation mechanism, this point corresponds to.net intermediate Language (IL).
Understanding Java NIO, there are a lot of tutorials on the web about this, this one is important to master, for high concurrency.
Java juc (Java. Util. Concurrent) and so on
4.Java multithreaded programming
Java threads: Concepts and principles
Java threads: Create and start
Java threads: Thread stack model and thread variables
Java threads: Transitions of thread state
Java threads: Synchronization and locking of threads
Java threads: Thread interactions, etc
Java network and server programming
The network structure
6. The TCP/IP protocol
Source code analysis
Introduce the classical design ideas used in the source code in detail, see how Daniel is to write code, enhance the technical aesthetic, improve the core competitiveness.
Common Design patterns
