    Default No such file or directory exist (help!)

    So I'm making this simple zombie simulation game wherein a player is given a situation and different options to choose. Whenever they make a decision I have an object that will write a letter within a file which is a number. This number indicates their score on depending on the decision.

    System.out.println("\n\t\t==================================================");
    		System.out.println("\t\t|                                                |");
    		System.out.println("\t\t| You have been hiding inside your house for a   |");
    		System.out.println("\t\t| few days now. Outside there are plenty of      |");
    		System.out.println("\t\t| Zombies outside. What will you do?             |");
    		System.out.println("\t\t|                                                |");
    		System.out.println("\t\txxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
    		System.out.println("\t\txxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx");
    		System.out.println("\t\t|| [1] Barricade the house                      ||");
    		System.out.println("\t\t|| [2] Go outside and fight the zombies         ||");
    		System.out.println("\t\t|| [3] Search for supply                        ||");
    		System.out.println("\t\t|| [4] Escape through the back                  ||");
    		System.out.println("\t\t==================================================");
    		System.out.print("\t\tWhat would it be?: ");
    		int ans1 = keyIn.nextInt();
     
    		switch(ans1)	{
     
    		case 1: HomeGame.home1a(); loop = false; break;
    		case 2: HomeGame.home1b(); loop = false; break;
    		case 3: HomeGame.home1c(); loop = false; break;
    		case 4: HomeGame.home1d(); loop = false; Score.addScore(); break;

    This is the code for the object (This is still just a testing so everything is short)

    	public static void addScore() throws Exception	{
     
    		try{
     
    		FileWriter outFile = new FileWriter("test.txt", true);
     
    		outFile.write("a"+"\r\n");
     
    		outFile.close();
    		}
     
    		catch(Exception e)
    		{
    		System.out.println("Something went wrong: "+e.getMessage());
    		}
     
    	}
     
    	public static void ShowScore() {
     
    	try {
    		int count = 0;
     
    		BufferedReader fileIn = new BufferedReader (new FileReader("text.txt"));
    		String S = fileIn.readLine();
     
    		while(S!=null)
    		count++;
    		System.out.println("line "+count+": "+S);
    		S = fileIn.readLine();	
    	}
     
    	catch(Exception e)
    	{
    	System.out.println("Something went wrong: "+e.getMessage());
    	}
     
    	}
     
    }

    The output I always get is: No such file or directory exist

    I like your style! Get something simple to work. Make sure you understand what's going on, then fill in the Good Stuff. That's Great! (And I don't tell folks that unless I mean it.)

    First of all, make sure that your error catching messages are distinguishable. Does the error come from addScore() or from showScore()?

    Maybe augment them to something like:

        public static void addScore() throws Exception  {
     
            try{
                FileWriter outFile = new FileWriter("test.txt", true);
                outFile.write("a"+"\r\n");
                outFile.close();
            }
     
            catch(Exception e)
            {
                System.out.println("addScore(): Something went wrong: "+e.getMessage());
            }
     
        }
     
        public static void showScore() {
     
          try {
            int count = 0;
     
            BufferedReader fileIn = new BufferedReader (new FileReader("text.txt"));
            String S = fileIn.readLine();
     
            while(S!=null)
            count++;
            System.out.println("line "+count+": "+S);
            S = fileIn.readLine();
          }
     
          catch(Exception e)
          {
            System.out.println("showScore(): Something went wrong: "+e.getMessage());
          }
     
        }

    Then, remove any files named "*.txt" in your directory and recompile and run the program.

    After running the program:

    Does the directory have a file whose name is the name of the file that you tried to write? If so, what are the contents of that file?

    Does the directory have a file whose name is the name of the file that you tried to read? If so, what are the contents of that file?

    Look at the error message. Does the directory have a file whose name is reported in the error message? If so, what are the contents of that file?


    Cheers!

    Default Re: No such file or directory exist (help!)

    I have changed the code of the object that does the file writing and reading. But I still get this error at the end when I try reading the file.

     
    ShowScore(): Something went wrong: text.txt (No such file or directory)

    I have seen the file on my workspace area named "text.txt" and within that file is the letter 'a' since it's only going to write once.

    Well, how the heck can I know what is going wrong if I can't see your changed code.

    Did you do what I suggested?

    With your original code, after erasing "*.txt" files and running the code, I found a code named "test.txt" which is what addScore() writes. The ShowScore() function, on the other hand was looking for "text.txt" which is what the error message said was missing. Notice "test.txt" is not the same as "text.txt"

    If you have changed your code, how about showing us? Otherwise I really can see no way of helping.


    Cheers!
