java - ReadFile cannot be resolved to a type -

i consider rookie , have searched hours on internet solve problem still no luck.

i want understand java , if explain detail highly grateful.

the problem in line

readfile file = readfile(file_name);  error message : "readfile cannot resolved  type." 

here code: filedata.java

package textfiles; import java.io.ioexception;  public class filedata {      public static void main (string[] args) throws ioexception {          string file_name = "d:/java/readfile/test.txt";          try {              readfile file = readfile(file_name);             string[] arylines = file.openfile();               int i;             (i =0; < arylines.length ; i++) {                  system.out.println( arylines[i] );             }          }         catch (ioexception e) {              system.out.println( e.getmessage() );         }      }        } 

and other code: readfile.java

package textfiles;  import java.io.ioexception; import java.io.filereader; import java.io.bufferedreader;  public class readfile {      private string path;      public readfile (string file_path) {          path = file_path;      }     int readlines () throws ioexception{          filereader file_to_read = new filereader(path);         bufferedreader bf = new bufferedreader(file_to_read);          string aline;         int numberoflines = 0;          while (( aline = bf.readline() )  != null) {              numberoflines++;          }          bf.close();          return numberoflines;     }     public  string[] openfile () throws ioexception {          filereader fr = new filereader (path);         bufferedreader textreader = new bufferedreader (fr);           int numberoflines = readlines();         string[] textdata = new string[numberoflines];          int i;          (i=0; < numberoflines; i++) {              textdata[i] =textreader.readline();         }           textreader.close();         return textdata;     } } 

try this:

readfile file = new readfile(file_name); 

in order initialize object it's class name should use new key word this:

classname objname = new classname(arguments); 

from rest of code seems know notion, nevertheless refer (or possible future visitors) this page.
