Hello,
I want to display my ArrayList in the text area like this:
jTextArea.setText(myArrayList);
But it gives me an error, because it can only set Strings, and my ArrayList is not a String.
How do I solve this?

How to display ArrayList in jTextArea?

What type of objects does your ArrayList contain?
Re: How to display ArrayList in jTextArea?
Class objects
ArrayList<MyClass> = new ArrayList();
Re: How to display ArrayList in jTextArea?
Obviously this doesn't compile. setText requires a String, not other objects. It's up to you to generate a new String that contains, for example, N lines where each line contains a text about an element.Originally Posted by Prog
I repeat, you have to do this with some specific code, it requires at least a for cycle, and some string concatenations (better if you use a StringBuffer/StringBuilder).

Re: How to display ArrayList in jTextArea?
Interesting. Perhaps you could write a toString() method for MyClass and use that to display the MyClass objects as Strings in the JTextArea.
Re: How to display ArrayList in jTextArea?
Yes Greg! I got it now!
What I did is the following:
jTextArea.setText(myArrayList.toString());
Works like a charm
Thank you!
Re: How to display ArrayList in jTextArea?
Yes, it works. But you are a bit limited by the format imposed by toString() of ArrayList.

Just in case you are unfamiliar - and depending upon your needs - a JList or JTable might provide more functionality and neatness when displaying Lists of data.
Re: How to display ArrayList in jTextArea?
The method append(String) in the type JTextArea is not applicable
for the arguments (ArrayList.Account.TransactionObject>)
