the piece of code i have works correctly, but i will have more than one array being written to the text area, i have got it to write to it, but they are all on the same line,
do you know what the return command is? so i can display each array on a seperate line.
Thanks.

Do us and yourself a favor, and post your code.

JButton01.addActionListener(new ActionListener(){
public void actionPerformed(ActionEvent event) {
// Temporary String Variable, to store the arrays.
String temp;
// initalises temp to an empty string.
temp = "";
Razor [ ] razors = museum.getAllRazors();
if(razors.length == 0) {
JTextArea01.setText("Museum has no Razors");
}
for(int i=0;i
temp += razors;
// HERE IS WHERE I NEED SOMESORT OF RETURN LINE!
JTextArea01.setText("All Razors " + temp);
}
}
});
this is it if you can make head or tails of it.

Try:
TextArea01.append( new Charecter( 13 ) );
I don''t know if that will work, because for some reason I''ve never had to create a newline in a text box before. I can''t think why not.
Try sun''s website:

Also the JAVA tutorial:

TextArea01.append( new Charecter( 13 ) );

To put each array entry on a separate line do something like this:
