as above.
e.g
int[] array = new int[can be any size]
joptionpane.showmessagebox(null,
"what to put here is the question"
"messageboxtitle"
joptionpane.informationmessage};
//dont correct the message box crap i was in a rush i know how to do it
e.g
array 1 = 1
array 2 = 5
array 3 = 3
array 4 = 2
the array can be any size thats the problem so i can't just put
"array 1"+ array[0]
"array 2"+ array[1] etc
i can use a for loop when outputting it in a dos window but what can you use for a message box?

that is likely not what was intended, as it shows a separate messagebox for each element of the array 
better would be something like
this will put each element of the array onto its own line.
When using Java versions lower than 1.5 use StringBuffer instead of StringBuilder.

better would be something like
Java Syntax (Toggle Plain Text)
StringBuilder builder = new StringBuilder(p.length); for (int i=0;i<p.length;builder.append(p[i++])) builder.append("\n"); JOptionPane.showMessageDialog(null, builder.toString(), "Printing results", JOptionPane.INFORMATION_MESSAGE);
this will put each element of the array onto its own line.
