Class members include member variables and member methods, and the syntax for defining classes is as follows:
class 类名称{//成员变量列表function成员方法1([参数1,参数2,……]){//成员方法1的具体实现}function成员方法2([参数1,参数2,……]){//成员方法2的具体实现}//其他成员方法}

A sessionfactory instance corresponds to a database where an application obtains a session instance from that object.4.SessionFactory is thread-safe, meaning that one instance of it can be shared by multiple threads being applied.5.SessionFactory is heavyweig
When you create an array of class types, members that are not initialized call the class's default constructor , and other constructors cannot and cannot be calledTherefore, when a class is to be used as an element type of an array, the class must have a default constructor! Otherwise, the array must be explicitly initialized with the specified constructor for each element! If the base class has a default constructor:Base array[3]; legal //3 members will call base's default constructor, base do
