JAVA - Overwrite file if exists
I would like to overwrite the file if it exists. I am writing to a csv file and I dont want to append to it but rather overwrite the file if it matches the name exactly.
How would I modify it?
Date now = new Date();
formatter = new SimpleDateFormat("MMddyyyy
s = formatter.format(now);
outputFile = "C:\\Files\\NJ" + s +".CSV";
// Error catching.
try
{
File file = new File( outputFile );
fileExists = file.exists();
out = new FileWriter( outputFile, true );
session.log( "Writing data to a file." );
if (!fileExists)
{
etc,etc,etc
}

Try passing "false" as the second parameter for the second parameter of the FileWriter constructor:
out = new FileWriter( outputFile, false );
out = new FileWriter( outputFile, false );
You don't need the second parameter at all. Just use out = new FileWriter( outputFile, false );
Sorry, i mean
out = new FileWriter( outputFile);
then there's no possibility of error
out = new FileWriter( outputFile);
then there's no possibility of error
