View Full Version : Write to File in java

June 3rd, 2010, 07:13 PM
I'm just starting out programing, and i have come across a problem with writing to a file. I lack the back ground knowledge to know why it inst working, as far as I'm concerned it all compiled fine. =(

public void MakeClientPage() //creating the initial page for the client
{ //Begin the write

System.out.println("Write to file....");
BufferedWriter Write = new BufferedWriter(new FileWriter(Name + ".html",true));

Write.write("<HTML><title> " + Name + "</title><BODY>"); //writes header
Write.write("<BR><BR><CENTER><LARGE>Client: " + Name + "<CENTER><LARGE>");
Write.write("<BR><BR> ");
Write.write("<B></I>Client Personal Info</B></I><BR>");
Write.write(" <TR> ");
Write.write(" <TD>Entry Date</TD><TD> Work in Progress</TD> ");
Write.write(" </TR>");
Write.write(" <TR> ");
Write.write(" <TD><b>Client Name </b></TD><TD> " + Name + "</TD> ");
Write.write(" </TR>");


}catch(IOException e)
System.out.println("There was an Error Writing the file");

}//End of catch

}//End of MakeClientPage

Name is declared else where. The program creates the file with the right name, but doesn't write a single thing to it. Any help would be appreciated.

Flush it?
Call Write.flush(); after you are done writing.

Then close the resource you opened

I tried Flushing it right before i wrote it, and it didnt seem to have an effect.
I got the example code from

Is that even current java syntax?

I guess i had to Write.Close(); inorder for it to actully write to the file.

Thats really odd, but i guess thats how its done =)

Well yeah, you have to call close() for various reasons.
Just, you have to call flush AFTER you write, not before.

I just read the .close() javadoc, and it call flush() just before closing the stream.

Glad it worked out

C# has some static methods for quick writing to a file like File.WriteAllText(), File.AppendallText(). But when write thorugh a StreamWriter same as in Jave, it should be closed afterwards otherwise no writing. I prefer static methods for my quick text processing tasks.
