1、利用System.getProperty()函数获取当前路径: System.out.println(System.getProperty("user.dir"));//user.dir指定了当前的路径 2、使用File提供的函数获取当前路径: File directory = new File("");//设定为当前文件夹 try{ System.out.println(directory.getCanonicalPath());//获取标准的路径 System.out....

只是好奇System.getProperty("java.io.tmpdir")何时返回"c:\temp"。根据java.io.File Java Docs的说法- 默认的临时文件目录由系统属性java.io.tmpdir指定。在UNIX系统上,该属性的默认值通常是"/tmp“或"/var/tmp";在Microsoft Windows系统上,它通常是"c:\temp”。当Java虚拟机被调用时,可以为该系统属性赋予不...

SecurityManager sm = System.getSecurityManager(); if (sm != null) sm.checkPermission(this); これにより、適切なアクセス制御検査が消費者コンテキスト内で確実に実行されます。事実、頻繁に使用されるハッシュ表およびアクセス制御の一覧は、多くの場合置き換えられ、GuardedObjectsのハッシュ...
