I have a little utility that does a search of a number of files. I had to create it because both Google & Windows desktop searches were not finding the appropriate lines in files. The searching works fine (I am willing to improve on it) but one of the things I would like to add to my util is a batch find/replace.
So how would be the bes...
Okay... so I have a fairly interesting error... I declare a FileWriter called file, and I have it go through the following for loops:
for (int i = 0; i < a.radtot; i++) {
file.write("" + i * a.rstep);
for (int n = 0; n < a.timetot; n++) {
file.write("\t " + T[n][i]);
System.out.println(T[n][i] + " " + n + " " + ...
this code is correct??
String note = "text.txt";
FileWriter file = new FileWriter(note);
Scanner sc = new Scanner(System.in);
System.out.println("Enter your name:");
String name = sc.next();
file.close();
How can I pass this file to the program as a command line argument???

There's a loop where we get certain data. Depending on the data, file writer needs to write to different files.
Is it a good practice?

I'm currently using FileWriter to create and write to a file. Is there any way that i can write to the same file every time without delete the contents in there?

Good morning all,
I'm having a few problems with a method in my C# code that should enable a DataGridView to be saved to a .txt file.
The code is as below:

I'm trying to write TIFF IFDs, and I'm looking for a simple way to do the following (this code obviously is wrong but it gets the idea across of what I want):
out.writeChar(12) (bytes 0-1)
out.writeChar(259) (bytes 2-3)
out.writeChar(3) (bytes 4-5)
out.writeInt(1) (bytes 6-9)
out.writeInt(1) (bytes 10-13)
Would write:

I am creating and writing to a file using the following pattern:
File afile = new File("C:/dev/ws/DataOrdering/data/" + thisDate

writer.close();
However for some reason only the first file is written to, after that the files...
Hi Everyone,
I have a piece of code that generates new data whenever there is new data available as InputStream . The same file is overwritten everytime. Sometimes the file becomes 0 kb before it gets written. A webservice reads these files at regular intervals. I need to avoid the case when the file is 0 bytes.
How do it do this? Wil...
I have a question in my mind that, while writing into the file, before closing is done, should we include flush()??. If so what it will do exactly? dont streams auto flush??
EDIT:
So flush what it actually do?

I was using the CreateText method to create an empty file (as below) in "App1". Then tried to have another application write to that file but it failed b/c it was locked. It was not unlocked until I closed "App1"

To fix this I can do this:
Dim sw As StreamWriter = File.CreateText(path)
sw.Close()
Why does ca...

I have chosen nearly 200 files to write on a position automatically on a particular time. Created a separate job names in Quartz scheduler. The job will be triggered on a time. I can read the files only after all the files have been written. I could not read after one file is written. I have closed the FileWriter after one file written. ...
My program is suppose to maintain a collection of Photos in a PhotoAlbum. It begins by reading a folder of photos and adds them to my PhotoAlbum. It then prints a menu that allows the user to list all the photos, add a photo, find a photo, save, and quit the program. Right now if I run my program it will add the 100 photos to the PhotoAl...
Hi I am having no problem writing to or appending to a file, the only problem is that as soon as I quit the program and then run it again, it creates a new file overwriting my original file. This is a problem, as I am using the text file to keep a running tally.
Is there a way to get an already created text file as an object and then ap...
Hi,
I want to write a new file with the Java FileWriter. I use it like this:
FileWriter newJsp = new FileWriter("C:\\user\Desktop\dir1\dir2\filename.txt");
Now the dir1 and dir2 currently don't exist. I want Java to create them automatically if they aren't already there. Actually Java should set up the whole file path if not already ...
