Question

我需要获取我的目录之一的绝对路径。因此，我单击属性以获取该绝对路径，并在我的代码中输入：

 Scanner sc = new Scanner(System.in);

 public void Find(String path) {
        System.out.println("Enter in location");

        path = sc.nextLine();
        try 
        {
            File inputFile = new File(path);
            Scanner reader = new Scanner(inputFile);
        }
        catch(FileNotFoundException e)
        {
            System.out.println("Try again file not found");
        }
    }

我试图通过用户输入获取目录的绝对路径，因此我通过在main方法中调用类来通过用户输入输入目录的绝对路径，并且得到：

Enter in location of file 
C:\Users\Trevor's PC\Documents\NetBeansProjects
Try again file not found

所以我的课或我尝试阅读它的方式一定有问题吗？

inputFile.getAbsolutePath();

尝试此操作以获取绝对路径

您无法将目录传递给Scanner，也不能尝试将其传递给我们。

File f = new File(fname); 
 //apply File class methods on File object 
    System.out.println("File name :"+f.getName()); 
    System.out.println("Path: "+f.getPath()); 
    System.out.println("Absolute path:" +f.getAbsolutePath()); 
    System.out.println("Parent:"+f.getParent()); 
    System.out.println("Exists :"+f.exists()); 
    if(f.exists()) 
    { 
        System.out.println("Is writeable:"+f.canWrite()); 
        System.out.println("Is readable"+f.canRead()); 
        System.out.println("Is a directory:"+f.isDirectory()); 
        System.out.println("File Size in bytes "+f.length()); 
    }

在Java中获取绝对目录路径？
