当我在netbeans中运行程序时，一切都运行得很好。 但是，当我尝试构建项目以创建它的Jar文件时，每个调用setListData（Object []）的行都会导致以下错误：
warning: [unchecked] unchecked call to setListData(E[]) as a member of the raw type JList jList1.setListData(people.allStudentsAttendance()); where E is a type-variable: E extends Object declared in class JList
我故意取消选中-Xlint，因为我收到错误：
Note: L:\Attendance\src\Attendance\AttendGUI.java uses or overrides a deprecated API. Note: Recompile with -Xlint:deprecation for details. Note: L:\Attendance\src\Attendance\AttendGUI.java uses unchecked or unsafe operations. Note: Recompile with -Xlint:unchecked for details.
之前我取消选中它并开始尝试调试错误。 Jar文件不起作用，经过几天的搜索，我无法弄清楚如何解决这个问题。提前谢谢
这是我的GUI代码~~

JList并且DefaultListModel在Java 7中变为generic。NetBeans在其生成的代码中禁止相应的警告，但您的代码仍未选中。你可以
