Saving contents of textarea

[Mulligan]

Hi. I am new here.

I have written a programme that calculates figures in textfields then displays them in a textarea. I was wondering if there is anyway to save the figures and text in the textarea. I know it would come under the ioexception and printerscanner. I was just wondering if there is an easy way to do it as the data is in the textarea, rather than having to write every entry that was previously in the textboxes into the ioexception.

Is there any examples of code any of you could provide or any suggestions to do this easily.

Thank you.

myTextArea.getText();

JTextArea (Java Platform SE 6)
-> JTextComponent (Java Platform SE 6)
--> JTextComponent.getText() (Java Platform SE 6)

Reading the Api's are often helpful. It you look JTextArea inherits methods from JTextComponent, JTextComponent has a getText() method which returns a String containing the information in the JTextComponent. In this case, your JTextArea.

This is a strange task.
What is a "ioexception"? How do write into it?

I think he meant IO to a file, or something similar.

Yep that is what I meant. I have already used the get.text function to get the figures from the individual textfields then displayed in the textarea. I want to save the conglomerated figures to the harddrive in a file format then reopen them again. I was wondering whether there is an easy way to this by getting the text from the textarea rather than the individual textfields. Then saving it to a file I can reopen.

A JtextArea inherits a write(Writer w) method from its parent class; I'd suggest you'd use that method instead of the getText() method.

Yes there is, are you familiar with java.io (Java Platform SE 6) ?

Try taking a look at BufferedWriter (Java Platform SE 6)

I did something similar by using a BufferedWriter connected to a FileWriter and simply used

myBufferedWriter.write(myTextArea.getText());

However I'm still fairly new to this, and JosAH's suggestion may work better. I would have to look into the proper syntax of his method to help you further.

First take a look at how the file output methods work. For a text file, you will be writing the output line by line.
A line being a String followed by the newline character.

Wow thank you for all your help. This is a wonderful start.

I will have to do some research then get back to you.
