Error: java.lang.ArrayIndexOutOfBoundsException

[fernando]

Hi, I want to make a multiplication table where the user can choose how many rows and columns the table has, i get a "java.lang.ArrayIndexOutOfBoundsException: 5
at Review.main(Review.java:26)" error...I don't get that, anyone got any ideas? anyways here's my code take a look

// The "Review" class.
import java.awt.*;
import hsa.Console;

public class Review
{
static Console c; // The output console

public static void main (String[] args)
{
c = new Console ();

int a, b;
c.print ("a/row:");
a = c.readInt ();
c.print ("b/col:");
b = c.readInt ();


int table[] [] = new int [a] [b]; // max for table

for (int row = 1 ; row <= a ; row++) //length of rows
{
for (int col = 1 ; col <= b ; col++) //length of columns
{
table [row] [col] = row * col;
c.print (table [row] [col] + " ");

}
c.println ();
}


} // main method
} // Review class

Thanks.

The first element of an array is at index = 0
The last element is at index = array.length -1
Trying to access an element at index = array.length will throw an ArrayIndexOutOfBoundsException.
Try this:

for (int row = 0 ; row < a ; row++) //length of rows
{
    for (int col = 0 ; col < b ; col++) //length of columns
    {
        table [row] [col] = row * col;
        c.print (table [row] [col] + " ");
