Relative paths can be used  but they can be tricky  The best solution is to know where your files are being saved  that is  print the folder   import java io File  import java util     public class Hangman1        public static void main String   args  throws Exception           File myFile   new File  word txt            System out println  Attempting to read from file in    myFile getCanonicalPath              Scanner input   new Scanner myFile           String in               in   input nextLine               This code should print the folder where it is looking for  Place the file there and you ll be good to go

Put the word txt directly as a child of the project root folder and a peer of src  Project Root     src     word txt   Disclaimer  I d like to explain why this works for this particular case and why it may not work for others   Why it works   When you use File or any of the other FileXxx variants  you are looking for a file on the file system relative to the  working directory   The working directory  can be described as this   When you run from the command line   C  EclipseWorkspace ProjectRoot bin  gt  java com mypackage Hangman1  the working directory is C  EclipseWorkspace ProjectRoot bin  With your IDE  at least all the ones I ve worked with   the working directory is the ProjectRoot  So when the file is in the ProjectRoot  then using just the file name as the relative path is valid  because it is at the root of the working directory   Similarly  if this was your project structure ProjectRoot src word txt  then the path  src word txt  would be valid   Why it May not Work  For one  the working directory could always change  For instance  running the code from the command line like in the example above  the working directory is the bin  So in this case it will fail  as there is not bin word txt  Secondly  if you were to export this project into a jar  and the file was configured to be included in the jar  it would also fail  as the path will no longer be valid either   That being said  you need to determine if the file is to be an embedded-resource  or just  resource  - terms which sometimes I ll use interchangeably   If so  then you will want to build the file into the classpath  and access it via an URL  First thing you would need to do  in this particular  case is make sure that the file get built into the classpath  With the file in the project root  you must configure the build to include the file  But if you put the file in the src or in some directory below  then the default build should put it into the class path    You can access classpath resource in a number of ways  You can make use of the Class class  which has getResourceXxx method  from which you use to obtain classpath resources   For example  if you changed your project structure to ProjectRoot src resources word txt  you could use this   InputStream is   Hangman1 class getResourceAsStream   resources word txt    BufferedReader reader   new BufferedReader new InputStreamReader is      getResourceAsStream returns an InputStream  but obtains an URL under the hood  Alternatively  you could get an URL if that s what you need  getResource   will return an URL  For Maven users  where the directory structure is like src main resources  the contents of the resources folder is put at the root of the classpath  So if you have a file in there  then you would only use getResourceAsStream   thefile txt

i think it always boils to the classpath  having said that if you run from the same folder where your  class is then change Scanner input   new Scanner new File  word txt     to Scanner input   new Scanner new File    word txt     that should work

Make sure when you create a txt file you don t type in the name  name txt   just type in  name   If you type  name txt  Eclipse will see it as  name txt txt   This solved it for me  Also save the file in the src folder  not the folder were the  java resides  one folder up

I have the same problem  but you know why  because I didn t put  txt in the end of my File and so it was File not a textFile  you shoud do just two things    Put your Text File in the Root Directory  e x if you have a project called HelloWorld  just right-click on the HelloWorld file in the package Directory and create File Save as that File with any name that you want but with a  txt in the end of that I guess your problem is solved  but I write it to other peoples know that  Thanks

Your file should directly be under the project folder  and not inside any other sub-folder   If the folder of your project is named for e g  AProject  it should be in the same place as your src folder    Aproject         src         word txt
