    Default array creation and inizialization in a class

    Hi everybody, just registered. I'm studying java and thers is something about array creation and inizialization that seems weird to me.

    class Test {
      private int[] array;
      array = new int[2];
    }

    Hi everybody, just registered. I'm studying java and thers is something about array creation and inizialization that seems weird to me.

    The following code gives an error at compile
    class Test {
      private int[] array;
      array = new int[2]; //<identifier> expected at compile time
    }

    But if I do the same inside a method, it works
    class Main {
      public static void main(String[] args) {
        int[] arrayM;
        arrayM = new int[2];
        array[0] = 1;
        array[1] = 2;
      }
    }

    And an other strangeness I can't figure out is that if I modify the first snippet as in the following, it works:
    class Test {
      private int[] array = new int[]{1,2};
    }

    Thanks in advance.

    seems weird
    Can you explain that?

    Use [] with code tags.

    inside a method, it works
    Most statements are not allowed outside of a method.
    Those that are allowed are mostly definitions and initialization.
