Question

What is the output of the following java class? Please state if you think there is an error and if so state what the error is:

Answer 1

```
class p
{
public static void main(String [] args)
{
int [] a = new int [10];
for (int i=0; i<10; i++)
a[i+1]=i;
System.out.print(a[3]);

}
}

Answer 2

Why is it throwing an exception? Where does the index go out of bounds?

Answer 3

when i=9 in the loop a[i+1] ==> a[10] is out of bounds because arrays go from [0] to [size-1] which in this case is [0] to [9]

Answer 4

Thanks, in a moment of ultimate inspiration, I decided to draw out the array in a table, and then I got it, who knew you could draw it out (ok, I did but I just didn't connect the two) =)
