我正在一个小程序中工作。它与 Eclipse 完美配合,但是当我尝试从控制台运行时,它给了我这个堆栈跟踪:
C:\Course Technology\src>appletviewer TestJAlienHunt.html
Path for file entered D:\Course Technology\AssignmentFinal\scoreFile.txt java.security.AccessControlException: access denied ("java.io.FilePermission" "D:\Course Technology\AssignmentFinal\scoreFile.txt" "read")

该文件具有读写权限,为什么我得到这个?
