simplest way to make 2d array to string

[Tamu]

Hi.

I am tired using double loop to print 2d-array on a console.

Somebody know a ready-to-use-class in java api that print 2d array to String?

Something similar to Arrays.toString-method.

I know of no simple methods that fit this bill. The only solution I can think of for simplifying the calling of a toString method on a 2-D array would be to create a wrapper class that held the 2-D array and create a toString override method that internally would use nested for-loops and a StringBuilder to build the String you desire.

Fubaable's recommendation is good, but even without that you don't need nested loops. Just call Arrays.toString in a single loop.

int[][] ints = {{1,2},{33,44},{555,666}};
for (int[] is : ints) {
   System.out.println(Arrays.toString(is));
}

Darryl's suggestion is a good one, but if you look at the code for Arrays.toString, you'll see that it uses a StringBuilder and a for-loop, and so Darryl's example still uses at its core nested for-loops.

OK, so I cheated a little on this post. ;)

thank you darryl. your code looks beautifull =)
