Saving files

Posted: May 12, 2004 9:30 AM

How would you make a simple button that will take info from textfields and save it to a file?

Have your class with the button implement ActionListener. When the actionPerformed method is invoked by the button click .. capture the text from your textfields and call your method to write those values to a file.

Do you have a sample code I could see because I am learning to program right now and I only have about 9 months of experience in programming.

When ever I save it will delete what was already in the file but I want it to add it to what is already in the file. So would I just append the textfield inputs or something like that?

When you create the object of FileOutputStream then pass true as its second argument. That way it won't overwrite the existing contents, rather it will append it. YOu can create file output stream as

FileOutputStream fos = new FileOutputStream (your_file_object, true);

Get a decent book on Java and Swing. This is so basic just about any tutorial will have the parts, it's only a matter of taking the pieces and putting them together.

button->actionlistener->filestream->file

Here's an example that uses a JFileChooser.

Post what your code if you still need help.
