how to print out an array in a message box

Nov 30th, 2004

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?

Hi,
Here is a small example how to print an array in Message Box
suppose p is an array:
for( int i = 0;i < p.length; i++)
{ JOptionPane.showMessageDialog(null, p[i], "Printing
results",JOptionPane.INFORMATION_MESSAGE);
}

Hopefully this would help and good luck.

that is likely not what was intended, as it shows a separate messagebox for each element of the array

better would be something like

 Help with Code Tags 
 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);
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.

When using Java versions lower than 1.5 use StringBuffer instead of StringBuilder.

How would you to the same to a two dimensional array?
