If text file is not being read  try using a more closer absolute path  if you wish  you could use complete absolute path   like this   FileInputStream fin new FileInputStream    Dash  src  RS  Test txt      assume that the absolute path is   C   Folder1  Folder2  Dash  src  RS  Test txt

While the answer provided by BalusC works for this case  it will break when the file path contains spaces because in a URL  these are being converted to  20 which is not a valid file name  If you construct the File object using a URI rather than a String  whitespaces will be handled correctly   URL url   getClass   getResource  ListStopWords txt    File file   new File url toURI

I could have commented but I have less rep for that  Samrat s answer did the job for me  It s better to see the current directory path through the following code       File directory   new File            System out println directory getAbsolutePath       I simply used it to rectify an issue I was facing in my project  Be sure to use    to back to the parent directory of the current directory         test conf appProperties keystore

The relative path works in in java using the   operator      means same folder as the currently running context     means the parent folder of the currently running context    So the question is how do you know the path where the java is currently looking   do a small experiment     File directory   new File           System out println directory getAbsolutePath       Observe the output   you will come to know the current directory where java is looking   From there   simply use the    operator to locate your file   for example if the output is      G  JAVA8Ws MyProject content    and your file is present in the folder MyProject simply use   File resourceFile   new File     myFile txt      Hope this helps

If it s already in the classpath  then just obtain it from the classpath instead of from the disk file system  Don t fiddle with relative paths in java io File  They are dependent on the current working directory over which you have totally no control from inside the Java code   Assuming that ListStopWords txt is in the same package as your FileLoader class  then do   URL url   getClass   getResource  ListStopWords txt    File file   new File url getPath       Or if all you re ultimately after is actually an InputStream of it   InputStream input   getClass   getResourceAsStream  ListStopWords txt      This is certainly preferred over creating a new File   because the url may not necessarily represent a disk file system path  but it could also represent virtual file system path  which may happen when the JAR is expanded into memory instead of into a temp folder on disk file system  or even a network path which are both not per definition digestable by File constructor   If the file is -as the package name hints- is actually a fullworthy properties file  containing key value lines  with just the  wrong  extension  then you could feed the InputStream immediately to the load   method   Properties properties   new Properties    properties load getClass   getResourceAsStream  ListStopWords txt       Note  when you re trying to access it from inside static context  then use FileLoader class  or whatever YourClass class  instead of getClass   in above examples
