Homework help please..

Question

I'm doing a homework assignment for school where i need to make a program that will ask user for filename, open the file and display the first 5 lines.. I have the text over and over again.. I'm just a little confused about this.. Even if i take a code out of the book and put into netbeans and try runing it i am getting the same error message. Is their something im missing.. I make a file in notepad that im trying to open and its not working.
ERROR MESSAGE
run:
Enter the filename you want to open FileToBeOpened
Exception in thread "main" java.io.FileNotFoundException: FileToBeOpened (The system cannot find the file specified)
at java.io.FileInputStream.open(Native Method)
at java.io.FileInputStream.<init>(FileInputStream.java:106)
at java.util.Scanner.<init>(Scanner.java:621)
at filereader.filereader.main(filereader.java:29)
Java Result: 1
This is the beginning of my program
package filereader;
import java.util.Scanner;
import java.io.*;

public class filereader {
     * @param args the command line arguments
    public static void main(String[] args)  throws IOException
        int MaxLines;
        //create a Scanner object for keyboard input.
        Scanner keyboard = new Scanner(System.in);
        //Get the filename.
        System.out.print("Enter the filename you want to open");
        String filename = keyboard.nextLine();
        //open the file
        File file = new File(filename);
        Scanner inputFile = new Scanner(file);

Answer 1

your file name entered is not correct in that Java is not looking for your file where you think it's looking. To find out where Java is looking, write a small program that simply calls:
public class Fu1
  public static void main(String[] args)
    System.out.println(System.getProperty("user.dir"));
}and you will know where Java is starting to look.
Or you could just type in the full path and file name.
