Jsp directory file operations

Jsp Tutorial Directory file operations

File file1 = new file ("c: tempmynote.txt"); // in windows
File file2 = new file ("/tmp/mynote.txt"); // in linux/unix

Check file path

Import java. io. file;
Public class mainclass {
Public static void main (string [] ){
File myfile = new file ("c:" + file. separator + "jdk1.5.0" +

File. separator, "file. java ");
System. out. println (myfile. getname ());
System. out. println (myfile. getpath ());
  }
}

Obtain remote images

Import java. io. file;
Import java.net. uri;

Public class mainclass {
Public static void main (string [] a) throws exception {

File remotefile = new file (new uri ("file: // index.htm "));
  }
}

Parent Directory

 

Import java. io. file;
Public class mainclass {
Public static void main (string [] ){
File myfile = new file ("c:" + file. separator + "jdk1.5.0" +

File. separator, "file. java ");
System. out. println (myfile. getparent ());
System. out. println (myfile );
  }
}

Determine if it is a directory

Import java. io. file;
Public class mainclass {
Public static void main (string [] ){
File myfile = new file ("c:" + file. separator + "jdk1.5.0" +

File. separator, "file. java ");
System. out. println (myfile. isdirectory ());
  }
}

Is it a file?

Import java. io. file;
Public class mainclass {
Public static void main (string [] ){
File myfile = new file ("c:" + file. separator + "jdk1.5.0" +

File. separator, "file. java ");
System. out. println (myfile. isfile ());
  }
}
