(?The main purpose of this system is to realize student information management, make student information management and office easier, thereby improving office efficiency and reducing management resources. The system needs to manage support identities and adopt the mode of logging in to the system. Because this system is in It can't run directly on the computer on our campus, and it is necessary to debug it from scratch to run it out. I think to avoid this situation, if it can't run directly on your computer, please follow the steps below to debug: First, open the database. java file, and compile it from scratch, then open the Land.java file privatevoidJudge(StringsqlString){if(database.joinDB()){if(database.query(sqlString))try{if(database.rs.isBeforeFirst()){ System.out.println(password is accurate);jf.setVisible(false);//Close the database connection database.close();newMain();}Comment out the newMain(); in it first, that is, //newMain(); Then compile Land.java from scratch, then compile other files except Main.java, and finally compile Main.java. The following operation is to open the Land.java file and remove the comments just now, that is, //newMain(); restores to newMain();, then compile the file from scratch, and then compile the Main.java file, and then run Main.java, it can be run, pay special attention to the order of compilation. If it still doesn't work, please connect with me, thank you, the username and password are all in the database. This information includes the following attachments:
