数据库你自己弄吧JAVA项目教室管理代码，我没时间弄JAVA项目教室管理代码了！初学得多动手哦
Q2: java教室分配管理系统
首先要设计表结构，表结构才是业务逻辑实现的最初的地方。一张教室表，一张教师表，一张教室场次（或者说是时间表），再做一张中间表管理场次表和教师表就行啦。
Q3: 在Eclipse下建立一个Java项目，实现在控制台上输出学生、教师的相关信息，见以下输入测试数据
第一步：在菜单栏window下拉菜单中的”show view“中找到”Console“打开并拖拽到eclipse工具内的适当位置。
第二步：在java代码中增加类似于”System.out.println()“方法，并在println方法中增加合适的参数值”success“（根据实际情况输入要输出的内容）。
第三步：在java类（含有main方法）中，右击”run as“，选择”java Application“运行即可实现控制台内容输出，效果如图，”success“已经打印在控制台中。
Q4: 基于java的题库管理系统源代码
楼主JAVA项目教室管理代码，JAVA项目教室管理代码我也需要这个JAVA项目教室管理代码，JAVA项目教室管理代码你现在还有这个源代码不JAVA项目教室管理代码？
Q5: 登录界面的java代码，分别有教师登录，管理员登录，学生登录，右边是用户名和密码，见图。
分三个包，自己建个包，导进去就ok了，数据库是access的。
