Is it really necessary to add a newline for each array element?

I lost a lot of time looking for my error and the problem was i declared all the elements on the same line. Is it really wrong?

You were probably getting the error because of how treehouse checks your code. Alessandro hit the nail on the head though, you don't need new lines.

Java does not care about newlines. You could theorically write all of your code on a single line. The imporant thing is that the syntax of the code is correct.

int[] numbers = { 1, 2, 3, 4 };

have the same meaning of:

int[] numbers =
{
   1,
   2,
   3,
   4
};

Watch out for semicolumns and columns: those are ESSENTIAL.
