Check if an array is sorted, return true or false

Question

I am writing an easy program the just returns true if an array is sorted else false and I keep getting an exception in eclipse and I just can\'t figure out why. I was wonder

Answer 1

public static boolean isSorted(int[] a)
{  
    for ( int i = 0; i < a.length - 1 ; i++ ) {
        if ( a[i] > a[i+1] )
          return false;
    }
    return true;
}

This function checks whether the array is in Ascending order or not.
