But the use of the digital library makes the performance of using the library to be more efficient by providing quick access to services and information. Modern libraries simply work using manpower and are time inefficient. Its encapsulation contents are as follows: provide corresponding constructors for book title, book author, book publishing house, library collection location, book borrowing status and ISBNCode variables set by imitating Chinese standard ISBN code, and rewrite toString() method in this class to display book information.The libraries are an organized collection of different sources of information where an individual can easily borrow the information in the form of a book/journals or can refer to the sources there itself.

In this case, like the previous cases, MVC framework is also used to separate the business layer and view layer, improve the maintainability of the program and reduce the coupling. It is used for users to borrow books existing in the libraryĪt the same time, the structure diagram of this case is attached (I'm sorry for my poor drawing) It is used by the administrator to modify the basic information of books in the library Used by the administrator to delete books in the library Used by administrators to add books in the library It is used for users to view all books existing in the library

In this case, it is divided into administrator side and ordinary user side, with different functional permissions. When you're ready, take our brains and you can do it JDK and IDE do not necessarily need to be unified. Case 3: Development team scheduling software based on Javaīefore starting to do things, you must prepare the following things.Case 2: Customer information management system based on Java.Case 1: Household income and expenditure accounting software based on Java.Previous case articles, interested partners can jump to check it by themselves! The corresponding source code is attached: It is estimated that it will be further developed after my own technology is improved. After a lapse of two weeks, I once again wrote a Java practice case - 'library management system', which is a simplified version of the library management system.
