Wierd Array Error

Question

So I was making a simple selection sort program that would read in an array and then sort it using the aforementioned method and received a very strange error. I have made similar programs before and never encountered this error and cannot find what has went wrong. Any assistance is appreciated. Here is the code and error.
import java.util.Scanner;
public class Q1assignment5
public static void main (String[] args)
int i, j, N = 0;
int [] a = new int[N];
Scanner keyb = new Scanner(System.in);
System.out.print("Enter the number of integers you want in the array");
N = keyb.nextInt();
System.out.println ("Enter the integers to be sorted: ");
for (i=0;i<a.length;i++)
a[i] = keyb.nextInt();
System.out.println ("The array sorted looks like this: ");
for (i=0;i<N;i++)
for (j=(i+1);j<N;j++)
if (a> a[j])
int temp = a[i];
a[i] = a[j];
a[j] = temp;
for (i=0;i<N;i++)
System.out.print (a[i] + " ");
And the out put/error
--------------------Configuration: <Default>--------------------
Enter the number of integers you want in the array 6
Enter the integers to be sorted:
The array sorted looks like this:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at Q1assignment5.main(Q1assignment5.java:29)
Process completed.
It is skipping the assignment loop so I believe the problem is located in the first for loop, but cannot see where.
