2D Array size

[Sasikanth Malladi]

Hi!
I've got a 2D array which I'm initializing manually. How do I find the number of columns in each row?
Here's my array:
int times[][]={ {5,22,12,30,19,17,22,36,10,22,15,30,8},
{9,45,18,46,7,17,14,50,23,18,25,15,7},
{7,18,7,30,15,25,12,30,10,25,12,20,9},
{11,20,8,19,15,16,14,14,19,18,15},
{22,24,23,17,10,6,19,8,14,9,9,12,8,20,6},
{25,20,22,10,21,12,24,9,30},
{10,45,20,42,7,65,29},
{4,22,14,24,16,19,22,12,20 }};
<h1>(How messy!)</h1>
Anyways, how do I use a 2 level nested for loop to go thru the elements? Is there a 2D equivalent of array.length?
Thanks,
sasikanth

Hi Sasikanth Malladi,
You were in Auburn right?. Nice to meet you here.

for (int i=0;i<times.length;i++){>
System.out.println(times[i].length);
}

Sorry!! something wrong when i tried to post it!! statements appeared to get mixed eventhough i posted it right

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

Hope this works.. I am typing it again!!
for (int i=0;
i<times.length;i++){>
System.out.println(times[i].length);
}

no use.. Moderators!! why is this sudden problem?. I am trying to type a simple for loop with i<times.length; it get messed up at that point?..>

Hi, Natarajan!
Yeah, nice meeting you here! Thanks for your reply but my array is an uneven array. Will this still work?

This forum thinks that the < followed immediately by times.length with no space between is an html code and therefore does not display as you would expect it to. If you put a space after your < , it will display properly. Notice your post above with extra spaces included.

Thanks Meriylon!!.
Yes Sasikanth. The loop will occur for arrays of any type and length.
for (int i=0; i < times.length; i++)
System.out.println(times[i].length);
Did you try this?
