deepEquals and equals

Hello,

pls can anyone tell me the difference between Arrays' deepEquals and equals method? Checked Java API, couldn't see any difference.

Thanks.

That's strange. When I looked, the entry for deepEquals() was much longer than the entry for equals().

So you're saying the difference in the methods is that one has a longer API entry?

;-)

import java.util.*;

public class DeepEqualsExample {

public static void main(String[] args) {

int[] a = {1, 2};

int[] b = {1, 2};

int[][] aa = {a};

int[][] bb = {b};

System.out.println("Arrays.equals(aa,bb)=" + Arrays.equals(aa,bb));

System.out.println("Arrays.deepEquals(aa,bb)=" + Arrays.deepEquals(aa,bb));

}

No, I'm making the trivial observation that if the entries have different lengths then they cannot be the same. And hence anybody who thought they were the same should look again.
