Currently want to job-hopping to big factory, so decided to review from the Java foundation and the underlying source code bit by bit, this series will mainly write some Java foundation and source code learning. Wait until you’re done and then try to write an essay or something like that.

JavaWeb

Java foundation: JavaWeb ServletConfig and ServletContext Java foundation: JavaWeb Request and Response Java foundation: Java foundation: JavaWeb JSP Foundation: JavaWeb EL expression

Java foundation classes

Java foundation: Integer — source code analysis Java foundation: String — source code analysis (A) Java foundation: String — String constant pool and INTERN (B) Java foundation: Enum — source code analysis

Java collection classes

Java Basics: HashMap – Source analysis Java Basics: ArrayList – Source analysis Java Basics: LinkedList – Source analysis Java Basics: TreeMap – Source analysis Java Basics: LinkedHashMap – Java source code analysis basis: HashSet/LinkedHashSet/TreeSet – Java source code analysis basis: the Vector/Stack – source code analysis

Java is a base class that is a little higher than the base
