conversion format does not match. Solution Process and achievements: Check the JDK manual and find the toString method of the Date class. The description indicates that all the Date classes will be converted into the form of "dow mon dd hh: mm: ss zzz yyyy, what is "dow, mon? On the surface, it seems to be "E" and "MMM". From the tracing results of debug, it looks like "e mmm dd hh: mm: ss zzz yyyy ". Howe

When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome. Why xpath? When using dom4j, we cannot obtain an element across layers. it must be obtained at one layer, which is very troublesome.Therefore, we can use the xpath technology to access a node more conveniently, which allows us to conveniently read the specified node. Xpath is usually used in combination with dom4j, and if you want to use xpath, you need to introduce a new

, also known as symbolic links, are equivalent to "shortcuts" in Windows, and creating soft links to a file is equivalent to creating a shortcut, which is small, so soft links are the same. This soft link store content is the path of the source file, so it will be very small, then create a shortcut will generate a file, create a soft link will also be reborn as a file, so the soft link is assigned an inode number, after a soft link to a file, you can access the soft link to access the source fil

Java code String STR = new string ("AAA "); How many string objects have been created in this line of code? The answer is 2, not 3.

, and only one when using using (e.g. If a select * is used, they will take precedence). Finally, natural is an abbreviated form of using: it automatically forms a using list of fields with the same name in two tables (only once for the same named field). If there are no fields with the same name, natural behaves like a cross JOIN. Example: T1: num | Name-----+------ 1 | A 2 | b 3 | c T2: num | Value-----+------- 1 | xxx 3 | yyy 5 | zzz Ru
