Question

鉴于java.io.File,即.exe文档,我如何发现档案属性,例如:所创造的大小和日期,以及我如何发现可执行财产中的数据,例如:档案版本?

Answer 1

值得一提的是,你在此再次提到国家食品安全扩展服务,而且直到最近(如Java SE 7)你才有机会在没有特殊身份的JNI ha窗的情况下进入这些场所。这应当与新的NIO2档案属性交接。其中一些属性,例如大小,是基本属性,而其他属性,如“用户”属性。

值得注意的是,介绍使用这一信息预报实例的最佳网页是。 http://www.ibm.com/developerworks/java/library/j-nio2-2/——如果你不关心其他APIC的事例,就搜寻“碎片特性”。

Answer 3

If you want the version of an executable file then that is almost impossible to do in the general case as there is no standard way of versioning the files (within that file format).

The other information should be easy to get. Checkout this answer: How to discover a File s creation time with Java?

Answer 4

参看<代码>java.io.File。它有如下方法:canExecute(>,length()。

Simple example:

You ll need some imports...

    import java.nio.file.Path;
    import java.nio.file.Files;
    import java.nio.file.Paths;
    import java.nio.file.attribute.BasicFileAttributes;

    String fileRoot = "";
    File file = new File(fileRoot);
    if (file.isFile()) {
        Path path = Paths.get(fileRoot);
        BasicFileAttributes attr;
        try {
            attr = Files.readAttributes(path, BasicFileAttributes.class);
            System.out.println("creationTime     = " + attr.creationTime());
            System.out.println("lastAccessTime   = " + attr.lastAccessTime());
            System.out.println("lastModifiedTime = " + attr.lastModifiedTime());

            System.out.println("isDirectory      = " + attr.isDirectory());
            System.out.println("isOther          = " + attr.isOther());
            System.out.println("isRegularFile    = " + attr.isRegularFile());
            System.out.println("isSymbolicLink   = " + attr.isSymbolicLink());
            System.out.println("size             = " + attr.size());
        } catch (IOException ex) {
            Logger.getLogger(MGSiap.class.getName()).log(Level.SEVERE, null, ex);
        }
    }
