    Default Can someone explain why the FILENOTFOUNDEXCEPTION keeps beign thrown?

    import java.io.File;
    import java.io.FileNotFoundException;
    import java.util.Scanner;
    public class TreeDriver {
     
    	public static void main(String [] args) {
     
    		Scanner input = new Scanner(System.in);
     
    		Tree test = new Tree();
     
    	String label ;

    		String message;
     
    		String filename = "sample.txt";
     
     
     
     
    		Tree family = new Tree();
     
     
    				try {
     
    					input= new Scanner(new File(filename));  
     
    					while(input.hasNextLine()){
     
    					label = input.nextLine();
     
    					prompt = input.nextLine();
     
    					message = input.nextLine();
     
    					family.root = new TreeNode(label,prompt,message);	
     
    					family.addNode(label, prompt, message, label);
     
    					}
     
    					input.close();
     
    					} catch (FileNotFoundException e) {
    					// TODO Auto-generated catch block
    					e.printStackTrace();
    				}
     
     
     
     
    	}
    	}

    I made sure the file and the class are in the same project but no matter what I do, it keeps throwing that exception. Please help I as soon as you can b/c this is part of an hw assignment

    Isn't the exception self-explanatory? The JVM cannot find the file. Either you have misspelled the name or the file is not in the correct location (most likely reason). Try using an absolute path instead or a relative one.

    I didn't misspell it. So how do I put the file in its correct location?

    I tried you suggestions and although I didn't run into any exceptions, when I tried to print info from the file, I received info that I didn't even put on the file. Can I get help resolving this issue?

    I cannot see you screen therefore I have no idea what your code looks like, what your file looks like, where your file is located. Basically I am relying on information provided by you which is next to nothing. How do you expect anyone to help?

    Put the file in the same folder as the class source file

    That might not always work. The JVM will look for the file relative to the working directory and not relative to the class file. The working directory may be different to the location of the class file. This is why I suggested using an absolute file path.

    Hello.
    Are you using any IDE? Or are you doing it on the console?
