Java static proxy-blocks, java static proxy Blocks
Definition of proxy mode: Provide a surrogate or placeholder for another object to controlaccess to it (Provides a proxy for other objects to control access to this object.). Create a proxy object in proxy mode to allow the proxy object to control access to the target object (the target object can be a remote object, an overhead object can be created, or a

Reference: http://uule.iteye.com/blog/1558891Static code blocks in Java are executed when the virtual machine loads the class, and only once. If there are multiple static blocks of code, the JVM executes them sequentially in the order in which they appear in the class, and each code block is executed only once.A non-static block of code is executed at the time of the class new instance, and every time a new
Three cases: Interpreting static code blocks and constructing code blocks.
I. Summary of static and non-static code blocks
1. Static code block:
Static code blocks are called first when a class is loaded (memory) and executed once. Static code blocks are often used to initia
Oracle tablespaces (tablespace), segments (segment), disk partitions (extent), and blocks are the allocation units used by Oracle to save database objects.
A segment is a database object that consumes storage space, such as tables, indexes, and rollback segments. When you create a table, a table segment is created. When you create a partition table, a segment is created for each partition. When you create an index, an index segment is created, object

The execution sequence of static blocks, main methods, constructor blocks, and constructor methods.
If you encounter a problem with the execution sequence of static blocks, main methods, constructor blocks, and constructor methods, add this note.
The question is the order in which the following java code is printed a

Fully conforms to the creation process described above.The following test loads the parent class and then creates the subclass object directly.
