java.io.FileNotFoundException: (No such file or directory) when running from eclipse

Question

I am writing to a file and want console output,

// TODO Create a game engine and call the runGame() method
public static void main(String[] args) throws Exception { 
    NewGame myGame = new TheGame().new NewGame();
    myGame.runGame();
    PrintStream out = new PrintStream(new FileOutputStream("output.txt"));
    System.setOut(out);
}

This gives me console output, but it throws the following exception:

java.io.FileNotFoundException: TheGame.txt (No such file or directory)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(FileInputStream.java:138)
    at game.main(TheGame.java:512)

The file does exist.

@meewoK: thank you. It still boggles my mind that the original poster never read his own question, saw that it didn't make sense, and corrected it. — Hovercraft Full Of Eels, Sep 10 '13 at 01:24
no offense, but we all start somewhere... and it's my first class. — user2644085, Sep 10 '13 at 01:28
No offense taken, but please remember that compilers are strict and unforgiving. Your question was a bit on the sloppy side, and you will want to train yourself to have low tolerance for such. Also posting a decent question, one that's easy to read and understand shows that you are taking your problem, this site and our help seriously. I look forward to watching your improvement over time. — Hovercraft Full Of Eels, Sep 10 '13 at 01:33

The file should be in contained within the root of your project.

When you execute a project in eclipse, the working directory is the most top level of your project.

Right click your project, click New>File, and make a txt file called "TheGame.txt".

You need to place it inside the src folder that's same as new FileOutputStream("your-file-name.txt")

-> and if it is inside a folder new FileOutputStream("./your-folder-name/your-file-name.txt")
