The default value of char type is \u0000, and if we want to initialize a char value with the default value, just create it as an instance variable and let the Java compiler do the rest of the work. public class SimpleTesting { char ch; // no initialization public static void main(...
At this point, the authenticatorConfig method will load the BasicAuthenticator class dynamically, creates an instance of the class, and adds it as a valve to the StandardContext instance. 此时,authenticatorConfig 方法将动态加载 BasicAuthenticator 类,创建该类的一个实例,并将其作为阀门添加到 StandardCont...
除了实现javax.servlet.http.HttpSession和org.apache.catalina.Session之外,StandardSession 还实现了java.lang.Serializable,使得Session对象可序列化。 The constructor of this class accepts a Manager instance, forcing a Session object to always have a Manager. 该类的构造函数接受一个 Manager 实例,强制使Sessio...
implementations is useful for obtaining and extracting the parameters from the keys and then using the parameters, for example as parameters to the DSAParameterSpec constructor called to create a parameter specification from parameter values that could be used to initialize a KeyPairGenerator object ...
Mapping a java.util.Date to the database requires additional code to convert to an Aerospike representation and back for example. Sub-objects which also need to be stored in the database must be handled separately. Changing the representation of the information between the database and the POJO...
