How are you running the program    It s not the java file that is being ran but rather the  class file that is created by compiling the java code  You will either need to specify the absolute path like user1420750 says or a relative path to your System getProperty  user dir   directory  This should be the working directory or the directory you ran the java command from

Generally  just stating the name of file inside the File constructor means that the file is located in the same directory as the java file  However  when using IDEs like NetBeans and Eclipse i e  not the case you have to save the file in the project folder directory  So I think checking that will solve your problem

When you run a jar  your Main class itself becomes args 0  and your filename comes immediately after   I had the same issue  I could locate my file when provided the absolute path from eclipse  because I was referring to the file as args 0    Yet when I run the same from jar  it was trying to locate my main class - which is when I got the idea that I should be reading my file from args 1

I have copied your code and it runs fine   I suspect you are simply having some problem in the actual file name of hello txt  or you are running in a wrong directory   Consider verifying by the method suggested by  Eng Fouad

In your IDE right click on the file you want to read and choose  copy path  then paste it into your code   Note that windows hides the file extension so if you create a text file  myfile txt  it might be actually saved as  myfile txt txt
