toString as output. Is there a way to format?

38
I have a program whose output goes to a simple jpanel.
I am using a toString to get it there, but as it is it shows up as one super long string of data.
Expand|Select|Wrap|Line Numbers
  1.     public String toString()
  2.     {
  3.     return ("Artist: " + artist + 
  4.     " CD Name: " + name + 
  5.     " Item Number: " + itemno + 
  6.     " Price: $" +price + 
  7.     " In Stock: " + nstock + 
  8.     " Stock Value: $" + value + 
  9.     " Restocking Fee: $" + restock + 
  10.     " Total Inventory Value: $"  + total);
  11.     }    
Is there a way to enter newline commands, carriage returns, or anything that may break this up in to two or three lines of data for simple readability?
I can find nothing.

Hi,
Put a newline character at the place from where u want to break ur string like this
Expand|Select|Wrap|Line Numbers
  1. public String toString()
  2. {
  3.       return ("Artist: " + artist + 
  4.       " CD Name: " + name + "\n" +
  5.       " Item Number: " + itemno + 
  6.       " Price: $" +price + "\n" +
  7.       " In Stock: " + nstock + 
  8.       " Stock Value: $" + value + "\n" +
  9.       " Restocking Fee: $" + restock + 
  10.       " Total Inventory Value: $"  + total);
  11. }
  12.  
Hope this will help you.

I guess you're putting that String in a JLabel, right? If so, JLabels also accept
html formatted Strings, e.g."<html>Hello<br>world</html>" will display two
lines of text.

Yes. I tried both and sent them a "report" of the results.

Neither worked, I am not sure if I misdescribed my code or what I am trying to do so I posted the entire class.

Hi Jos, thanks for the reply.

I did try it, implimented as so:
Expand|Select|Wrap|Line Numbers
  1. return <html>("Artist: " + artist +
  2.     " CD Name: " + name + 
  3.     " Item Number: " + itemno + 
  4.     " Price: $" + formatter.format(getPrice()) + 
  5.     " In Stock: " + nstock + 
  6.     " Stock Value: $" + formatter.format(getValue())  + 
  7.     " Restocking Fee: $" + restock + 
  8.     " Total Inventory Value: $"  + formatter.format(getTotal()));</html>
but all I get are "illegal start of expression errors. I put the tags inside the parenthsis, removed the parenthesis, tried all kinds of variations with them, but no matter where I put them I get errors.

Nonono, not like that; read my reply again. It should be something like this:

Expand|Select|Wrap|Line Numbers
  1. return "<html>Artist: " + artist +"<br>"+
  2. " CD Name: " + name + "<br>"+
  3. ...
  4. +"<html>";
  5.
