circumstances to 8 screen around to display. This makes it difficult to read a program or modify a program. It is therefore advisable to extract the block that completes the comparison of independent functions as a single function. A block that accomplishes the same or similar function is extracted independently of a sub-function. It can be found that the simpler the upper-level function is, the more specific work is done by invoking a few sub-functions, the more the underlying function complet

1, Java is an object-oriented language, not simply as a script to use. From the basics, don't start with spring, EE, Hibernate, and EJB.2, do not impetuous, should be solid first to learn the Java language, and then according to the Java itself learning laws, step by step to learn.3. Never start learning from IDE tools (JBuilder, Eclipse, and NetBeans), the

example:What exactly is boxing and unpacking, boxing is that the compiler performs a boxing operation after the underlying type is changed to the corresponding object type, and the reverse is the case. The following blog is a special introduction to Java Boxing and unpacking to share with youHttp://www.cnblogs.com/dolphin0520/p/3780005.html= = and equals I used almost every day, before this I did not care too much about the differences, and later loo

due to the time and space required for the copy-on-write operation. Second, your program does not need collection to have the most up-to-date information, iterator only with collection information at the time of creation. consider using multiple collection.Although some collection have minimal synchronization, these synchronization processes are problematic when there are multiple threads involved. Consider using Multiple segmented Collecton algorithms are used to replace multiple thre

is better to reuse objects instead of creating new objects of the same functionality every time you need them.In addition to reusing immutable objects, you can reuse mutable objects that are known not to be modified.To use the basic data type, try not to use the corresponding encapsulation class.6th: Elimination of expired object referencesYou can't think of a garbage collection mechanism, so you don't have to think about memory management.For exampl

technologies, there is no need to download plugins or small programs.Ajax has a lot of merit, and it is these strengths that reflect its shortcomings (of course, the shortcomings can be overcome).Disadvantages:1. Security issues2. Support for search engines is relatively weak.3. The exception handling mechanism of the program is broken.4. The original intention of URL and resource location is violated.Actual combata simple, but useful example: TheJava version asynchronously verifies that userna
