    Hello ,

    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};
       }
