Re: Array in Constructor
You're not using correct Java syntax for arrays. You can only create array literals if you create it at the same time that you declare the array. So this is OK:
class arra { int[] q = {1,2,2,4,2,2,2,2};
but this isn't
class arra { int[] q; public arra() { q = {1,2,2,4,2,2,2,2}; }
