File output help

[Row]

Hi,

I am having trouble writting from a JTextArea to a flat text file (locally)

I have tried using string tokenizer to tokenize the string first but with no luck,
Im stuck on the one

im a newbie so please take this into acount.
my snippet is below

//Post New Item from TextArea - To Vector, - then to Text File.
void postNewItem () {
try {
String Contents = singleTextArea.getText();
BufferedWriter output = new BufferedWriter( new FileWriter(urlTx) );
testVec.addElement(Contents);

Enumeration eNum = testVec.elements();
while (eNum.hasMoreElements()){
String pointer = (String)eNum.nextElement();
System.out.println("writen to file "+ pointer);
output.write(pointer);
output.close();

}//end while

First, you need to define "having trouble". Do you get an exception?
If so, what is it? Do you get a compiler error? If so, what is it?

A few comments on the code:

1. The output.close() is inside your while loop. That means your file
will be opened once, but closed for each element of testVec. Probably
not what you want.

2. The formatting is such that it's difficult to understand how your
code is organized. It's conventional to indent the body of a block.
This may have confused you and contributed toward your misplacing the
close() statement.

why do u need a vector anyway?

Just get the text and write it to a file:

String contents = singleTextArea.getText();
BufferedWriter output = new BufferedWriter( new FileWriter(urlTx) );
output.write(contents);
output.close();
