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.

☆ Get all the table names of the database, all the column names of the tableSelect name from sysobjects where xtype= ' u '
Select name from syscolumns where id= (select Max (id) from sysobjects where xtype= ' u ' and name= ' table name ')
☆ 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
