the first time. When a program creates the first reference to a static member of a class, the JVM uses the ClassLoader to find the same name based on the class name- .class once the object of a class Class is loaded into memory, it is used to create all the objects of the class. A constructor is also a static method of a class, and using an new operator to create a new object is treated as a reference to a static member of the class.Note Exceptions: If a static final value is a compile-time co
Java uses a class object to implement its own RTTI capabilities-even if all we have to do is work like styling. The class class also provides a number of other ways to facilitate our use of rtti. The must first obtain a handle to the appropriate class object. As shown in the previous example, one approach is to use a string and a Class.forName () method. This is very handy because you do not need an object of that type to get the class handle. However, for a type that is of interest to you, if

they can be automatically converted to the same data type. During automatic conversion, the system converts low-precision data types to high-precision data types. In UNION statements that contain multiple queries, the execution sequence is from left to right. Brackets can be used to change the execution sequence. For example, query 1 UNION (query 2 UNION query 3) INTERSECT. EXCEPT t INTERSECT is the intersection. distinct t indicates the difference set. select user_id from user intersect select
