How to use Enhanced for loop with 2D array

Hi everyone, Has anyone try to use the Enhanced for loop with a 2D array?
How do you set it up? Much thanks for anyone providing hints

You need two enhanced for loops for your iteration. Try something like this:

Why wait for someone else ?
Why dont you try it yourself ?
There is no other better way to learn it,I think.

Thanks for the ideas provided.

Looks like Garrett beat me on this by a few seconds

I had a similar piece of code on my mind as posted by Garrett.
But its the ranch policy to help people learn on their own so I refrained from posting it.

There's no such things as a 2D array; in Java all arrays are one-dimensional. When you declare int[][] you are actually telling the JVM you want an array and its members are each arrays. Look for the short[][] example in Java Language Specification �10.2.

You are right Campbell, there is no such thing as 2D array. But the term is widely used to mean an array whose individual elements are arrays.I think the reason behind this is the use of such arrays in matrices and 2D transforms.

You're right of course. It's always a judgment call as to how much to actually hand to a poster, and how much to let them figure out on their own. In this case I made the judgment that the code was trivial enough that giving away the answer wasn't too harmful.

Aren't there languages which really use 2D arrays? Then it might be that people forget Java is different in this respect. Note the Sun publications never say an array can be 2D.

Pascal / Delphi supports full multi-dimensional arrays, but also supports arrays of arrays.

Thank you, Rob.

Hmm thats true

As Garrett says, it is always a nice decision about how much to show a poster, but I think I would have done the same.

Even I would have done the same but after another post.
Anyways I think Garrett's view is justified.
