FileNotFoundException on .dat file

Propably it's simple error but I'm stuck. I keep a .dat file with a text I want to read in the program in the same package as main and base class, and I've got a FileNotFoundException. I tried to change the file on .txt, getting the URI syntax, but that didn't help. Where's the point?

The main class:

package syseks;


import java.io.FileNotFoundException;
import java.net.URISyntaxException;


public class main {

public static syseks.base ba;
public main(syseks.base ba){
    ba = this.ba;
}

public static void main(String[] args) throws FileNotFoundException {
    // TODO code application logic here

    ba = new base();
    String[] py = ba.loadData('p');
    System.out.print(py);
}

}

And the loadData method from base class:

public String[] loadData(char param) throws FileNotFoundException{

    List<String> strlist = new ArrayList<String>();

    if(param == 'p'){
        Scanner sc = new Scanner(new File("py.dat"));   //HERE'S THE CRASH
        while(sc.hasNextLine()){
            strlist.add(sc.nextLine());
        }
    }
    else{
        Scanner sc = new Scanner(new File("wy.dat"));
        while(sc.hasNextLine()){
            strlist.add(sc.nextLine());
        }
    }

    String[] da = strlist.toArray(new String[0]);

    return da;
}

Display the current directory using System.getProperty("user.dir"). Make sure it's the directory in which you've saved the .dat file.

Supply an absolute path to the File constructor argument. Something like:

Scanner sc = new Scanner(new File("/home/foo/proj/myapp/src/syseks/py.dat"));
