if something fails. if you do not know how to do this, then a reimage of the SD card may be necessary. assuming this is not an issue for your configuration, continue onward:

is a annotated tag):
$ git tag-a v1.1 1a410efbd13591db07496601ebc7a059dd55cfe9-m ' Test tag '
This is the SHA-1 value of the object being created:
$ cat. git/refs/tags/v1.1
9585191F37F7B0FB9444F35A9BF50DE191BEADC2
Now you can run the Cat-file command to check this SHA-1 value:
$ git cat-file-p 9585191f37f7b0fb9444f35a9bf50de191beadc2

It is worth noting that this object points to the SHA-1 value of the

constant pool. So the relationship between C, Chenssy, pool chenssy should be: c--->chenssy---> Pool chenssy. The whole relationship is as follows:
Through the above figure we can very clearly understand their relationship. So we modify the value in memory, and he changes it all.
Summary: Although a, B, C, and Chenssy are different objects, we can understand them from the internal structure of string. String c = new String ("Chenssy"), although the content of C is created in the heap, but his

the prototype chain of another object.For differences between the two methods, see JavaScript isPrototypeOf vs instanceof usage.
Only use prototype chain for inheritance
Disadvantages: 1. The prototype property of the reference type value will be shared by the instance; 2. When creating a child-type instance, parameters cannot be passed to the super-Type constructor.

☆ Recursive query dataRecursive queries in SQL statements SqlServer2005 and Oracle two versions
Using Oracle before, and finding it useful for recursive queries, I studied SQL Server and found that it also supports recursive queries in SQL
An example is pro
