array[k] = number;

Well, an ArrayIndexOutOf BoundsException means you're trying to access an element of an array that doesn't exist. Now, arrays are 0-indexed, which means they have array.length elements, starting at 0. Thus, what must the index of the final element be and where does your code try to move beyond that element?

I m getting this error while i m trying to run my program and i don't understand why that happens.
This is where it happens: -
-
int array[]= new int[12];
-
-
for(int k=1; k<=array.length; k++) {
-
-
System.out.print(k+ ":");
-
-
int number = sc.nextInt();
-
-
array[k] = number;
-
Just count: if an array has twelve elements their index values are: 0, 1, 2 ... 11
kind regards,
Jos
Tnx a lot guys i ve fixed it

When you don't need the array index in the loop (which is the case at least half the time, I bet) you can use the new enhanced for loop syntax, introduced in 1.5: - public class LoopExample {
-
public static void main(String[] args) {
-
int[] primes = {2, 3, 5, 7, 11, 13, 17, 19};
-
for(int p : primes) {
-
System.out.println(p);
-
}
-
}
-
}

Array indexes in Java is zero based. So if you declare a array of size 25. You can use only 0-24 element. There is no 25th index. 25th element present in 24th index.
And i suggest you to modify the code littler bit.

Hello all;
I'm trying to debug an issue with a java script called, SelectSockets.
It appears to be a fairly common one found on the web. I downloaded
the SGI Java v1.4.1 installation from SGI's webpage and installed it
using SGI's swmgr application. The installation was very straight
forward and there were no errors when I installed the package.
Then I ran /usr/java2/bin/javac SelectSockets.java to make the
SelectSockets.class file.
