Just a quick query hopefully.

System.out.println(); - when shoved in a for loop does quite a nice job outputting an array/iterator full of stuff.

Is there anything that I can use to do it in a gui? like a scrollable gui element sort of like a textbox I guess.

How would I do it?

off the top of my head, define your text area, then use
Code: [Select]

tJTextArea.append("Text");

where tJTextArea is the name of your text area

Would I need to make a string buffer for that and keep adding to it with \n between each line and then output it in one go?

or could just use

jTextArea.print(array[j]);

and it would make a lovely new line all of itself?

cant you just do

for (all elements i of array) {

 textarea.append(array + "\n");

}

Yea.....

Code: [Select]

while(array[i]!="\0")
{
   tJTextArea.append(array[i] + "\n");
   i++;
}


would do the same thing and would work for a flexible sized array

Ahh hell not so good.

"non static method append cannot be accessed from a static context."

Got around it :)

Used a StringBuilder object (WOO!!! so much faster than a stringbuffer, thank god for Java 1.5)

if youre using java 1.5 you can even use a foreach loop

for (String str : array) {
    textarea.append(str + "\n");
}
