of extensibility is goodCons: Creating generic-related instances troubleWhen used, the generic type is fixed once the parameter is passed in, resulting in a single type (for example, two generic factories above, you can see two different types)Generics are equivalent to adding a parameter to a type, similar to a method with parameters, the parameter of a method is a variable that declares a data type, a parameter is enclosed in parentheses, the passed argument is a value or an object of a data

But the trick here is to catch the exception at the right level so that your program can either recover meaningfully from the exception and continue without causing a deeper error, or provide the user with clear information, including directing them to recover from the error. If your method is not competent, then do not handle the exception, leave it behind to capture and deal with it at the right level.ConclusionExperienced developers know that the biggest d

Starting with tutorial (10), you have moved from learning the basic syntax of a single class to learning about relationships between multiple classes. In tutorial (10), we learned the relationship between class and class length, association and dependency. To maintain a 1-many-to-many relationship, in the tutorial (11), we learned the array. In addition to associ

XML is a widely used technology for data transmission and storage. Java provides a variety of APIs to parse XML, such as DOM, SAX, StAX, and JAXB. There are also some other APIs for parsing XML, such as JDOM. The purpose of this tutorial is to explore using different types of APIs to parse XML and learn to use XML to execute some common tasks.
