    Default 'Can't find file' error

    I can't find why this is not working. Here's my code, and then the error.

    import java.util.*;
    import java.io.*;
    public class CordreyLab6 {
    	public static void main(String[] args) throws IOException {
    		// get user input for file name
    		Scanner console = new Scanner(System.in); // for user input of file name
    		System.out.println("Please enter a file name: ");
    		String userFile = console.nextLine();
    		// read file and  pass to process method
    		Scanner input = new Scanner(new File (userFile));
    		processFile(input, console);
    	}// end main

    The error is:
    Please enter a file name:
    Exception in thread "main" java.io.FileNotFoundException: Lab6Input.txt (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.util.Scanner.<init>(Unknown Source)
    at CordreyLab6.CordreyLab6.main(CordreyLab6.java:17)

    I've put copies of the text file in all the folders I think I could be looking in- the class folder, the c:\root, the src folder, under the sink. I wish I knew what folders and files were created when Eclipse creates a java program. Obviously there is quite a bit more going on than just the source code folder. I don't know where the program is expecting to find the file, so I'm just guessing on where to put it. I suspect there is a better way.

    Thank you so much for the help!

    You can find out. Create a new File, write it, then invoke the File.getAbsolutePath() method on your new file and print out the result. In theory, that should give you the exact path.

    When asking for help, please follow these guidelines to receive better and more prompt help:
    1. Put your code in Java Tags. To do this, put [highlight=java] before your code and [/highlight] after your code.
    2. Give full details of errors and provide us with as much information about the situation as possible.
    3. Give us an example of what the output should look like when done correctly.

    you can add this
    final class manusia {
    int tinggi, berat;
    void bernyanyi(){ System.out.println(“Tralala..lilili”); } }
    class bapak extends manusia { <class body > }// salah
