Review the file class of Javaio

The file class is the only class in the IO package that represents the information for the disk file itself, not the contents of the files

The file class defines some platform-independent methods to manipulate files,

Directories in Java are used as a special type of file, and the list method can return all subdirectories and filenames in the directory

The path delimiter under UNIX is (/), the path delimiter under DOS is (\), and Java can correctly handle both path separators

Demo

Determines whether a file exists, is deleted, does not exist, and creates

Code Snippets

File F = new file ("1.txt");

if (f.exists ()) {

F.delete ();

}else{

F.createnewfile ();

}

System.out.println ("File name" +f.getname ()); Get the file name

System.out.println ("File path" +f.getpath ()); Get file relative path (path includes file name)

System.out.println ("File ASB Path" +f.getabsolutepath ()); Get the file absolute path

System.out.println (F.exists ()? " Exists ":" Not Exists "); Determine if a file exists

System.out.println (F.canread ()? " Read ":" not read "); Determine if a file is readable

System.out.println (F.isdirectory ()? " Directory ":" Not being directory "); Determine if a file is a directory

System.out.println ("Filed last Modifield Time" +f.lastmodifield ());//File Latest modified

System.out.println ("File name" +f.getname ()); Get the file name
