Java file path in Linux

Question

I have a rather silly question  but I haven t been able to find a solution for this    When I try and read a file I get a  file not found error  is runtime  It compiled the file though   I am on Linux  so I use the statement something like   Scanner s   new Scanner new File  home me java ex txt       and it gives me a runtime rror    home me javaException in thread  main  java io FileNotFoundException  home me java ex txt  No such file or directory  at java io FileInputStream open Native Method  at java io FileInputStream  lt init gt  FileInputStream java 137  at java util Scanner  lt init gt  Scanner java 653  at test main test java 14    I tried changing every possible thing along the lines of filenames  but nothing seems to work   Any clues as to why this is happening  where does java look for files by default

Looks like you are missing a leading slash. Perhaps try:

Scanner s = new Scanner(new File("/home/me/java/ex.txt"));

(as to where it looks for files by default, it is where the JVM is run from for relative paths like the one you have in your question)

I think Todd is correct  but I think there s one other thing you should consider  You can reliably get the home directory from the JVM at runtime  and then you can create files objects relative to that location  It s not that much more trouble  and it s something you ll appreciate if you ever move to another computer or operating system   File homedir   new File System getProperty  user home     File fileToRead   new File homedir   java ex txt
