How we can copy the component of a jtextarea into a file??

Hello all,
I would like to ask how i could copy the component of jtextarea into a file as a txt.file?
In my project i ask the user to write something in a jtextarea and i want the component of the jtextarea that user has typed to be copied into a file..
Does anyone have any idea?

Thanks in advance!!! :)

Take a look at the JTextArea methods inherited from JTextComponent, you may find something useful.

Hint: You'll be looking for a method that takes a Writer as a parameter.

db

javax.​swing.​text.​JTextComponent.write()

if you don't like this one, you can use "getText()" and manually write the String return value into a file.

Please stick with the method suggested by Darryl. Doing the work your self means you won't have the proper "newline" string added to your file depending on the OS you are using.

i've never tested this option with the newline in text.. and it's true.. i've tested it now.. if i write into a file the newline char '\n' it become something unreadable.. so i withdraw what i said in the second part of my post... use the write() method.

I tried to use this block of code but it doesn't work :S

Writer output = null;
File file = new File("out.txt");
output = new BufferedWriter(new FileWriter(file));
output.write("message"+getComponent(JTextArea1));
output.close();
} catch (IOException ex) {
Logger.getLogger(ptx.class.getName()).log(Level.SE VERE, null, ex);
}

Does anyone have any idea? :)

he did.. but i think he confused the write() method of BufferedWriter with the write() method inerithed by the JTextComponent class (the one suggested by Darryl).

you should call something like:

Code:

---

myjTextArea.write( myWriter );

---

where myWriter refeer to the file you want to write.

This method stores the contents of the model into the given stream. By default this will store the model as plain text (javadocs).

Thanks all for your response. :)

It does work but i want to ask something more.. In my project i want 2 methods to write in this file i call out.txt but when the second method is being called then everything that the first method wrote is erased.. I tried to use the special character \n but it didn't work :S

any ideas?

Read the API specs for FileWriter. There is a constructor which takes a boolean to indicate whether to append the data or not.

Thanks again guys i found the reason why this happened.. :)
