How JSP traversed

How JSP traversed

The purpose is to get all file names in a certain directory.

File has 2 methods to be used for you:

1, String [] list ();

2, file [] listfiles ();

When using the for loop, the file name will be traversed. After traversing, inserting the database is very simple -

The following code experiments are passed: {list all file names under DIR, except for the directory name}

CODE:

Import java.io. *;

Public class test {

Public static void main (String [] args) {

Try {

File Dir = New File ("D: / CODES");

String [] fs = dir.list ();

For (int i = 0; i

IF (fs [i] .indexof (".")! = - 1)

System.out.println (FS [i]);

}

}

Catch (Exception E) {E.PrintStackTrace ();

}

}
