I am working on a project that requires the main system, EmployeeSystem to be able to open a file with JFileChooser, and then write to that file, run a payroll system on it, and search it for a particular employee using a directory system. I am struggling right now to get the file output working. The method specifically that is not working is the addEmployee() method. If I comment that method out the class compiles perfectly, and I am able to select a file through JFilechooser. So I know that part is working fine. However when I attempt to compile with addEmployee in the code, I get compiler errors because it doesn't recognize outStream. I'm not very strong on try catch finally statements, as I just learned them today. I think that I set it up right but I'm not positive.

Help is appreciated.

There is no such method as you try to use. FileOutputStream is only able to work with byte array, there fore before you pass data to it you need to convert it to byte array

EmployeeSystem.java:126: cannot find symbol
symbol  : variable outStream
location: class EmployeeSystem
		outStream.close(); }
		^

Declaration of outStream was done inside try statement therefore this object is available only there. You will need to make declaration outside, something like this would sort it out

FileOutputStream outStream ;
try {
	outStream = new FileOutputStream(mainFile);	
} catch (IOException e) {
//error statement
} finally {
	outStream.close(); }

The other two errors are similar as the above
Have look at this tutorial on the use of FileOutputStream, if it is still not clear you more then welcomed to ask more questions

Thanks a lot. I went and looked up a method to write the text directly to the file and decided to use FileWriter instead. It's working fine now except for one small problem, when it outputs value to the file it overwrites and erases everything that was in the file and adds the new data. How do I get it to only add on the next line? This is the new code I am using, and the file I am attempting to write to. Would I have to make it loop through each line till it finds a blank one? Or is there a simpler way?

And how would I make each value in the text file be separated by a single space? I'll probably figure this out in a bit, I'm hoping it's a simple formatting issue.

Thanks again.

Thoroughly reading the documentation would help you in the long run. :-)

I read the documentation much more thoroughly this time, although I am not always able to understand it all. I then modified the code so that it appends to the end of the file, and the modified the variable assignments so that a space is added to the front of each. Now it prints mostly right, however I am having a hard time making it print all on the last line. If I just type out.print for each one, they all print on the same line as the bottom entry, if I make employeeType an out.println all the other variables print on a new line, but employeeType is still stuck on the second to last line appended to the old data. Any ideas as to how I can get it to print all the variables to the same new line?

out.print("\n");

out.print(System.getProperty("line.separator")); or just make the OP use the BufferedWriters ' newLine() method.
