printing 2D arrays

[JS]

Hi all, Im just learning Java and was wondering if there is any way of
displaying a String[][] in a grid form. I have managed it using loads of
System.out.println statements printing each row at a time but i need to be
able to print it in a text area or similar, as long as its in a 15 x 15
square grid i dont mind how. Any ideas welcome. thanks in advance

I'm guessing your implementing the String[] [] into a GUI output. You
can simply create a new instance of a JTable passing it the array. If
you don't like the look you can change it using the methods of the
JTable class.

Alternatively you can simply concatenate all of the strings into one
string. Create a temporary string and then concatenate each string from
the array into the temp one, including all the formatting you have
already done. Then create a JTextArea, passing it the temp string.
Hope this helps

strArray[][] has your data.

for(int i=0;i<strArray.length;i++) {
for(int j=0;j<strArray.length;j++) {
System.out.print(strArray[j]);
}
System.out.println();
}

Thanks for your help but how do i specify which component it goes into. its
for a GUI output that i need it and at the moment i have a TextArea but cant
print multiple lines with the right formatting (the right format being a 15
x 15 square grid). how do i say "print to that area" so to speak?

PS I forgot to say, that I did try System.out.println("...../n.........");
but no luck, it just printed /n in the line

If this is a GUI based effort, use a JTable.

2d array print

i think if u can print it like this
int[][] s={{1,2},{2,3},{4,5}};

for(int[] a:s)
System.out.println(Arrays.toString(a);

or just
System.out.println(Arrays.deeptoString(s);

but in the second case u wont get it as grid.
