Java Initialize an int array in a constructor

Question

I have a class and in that class I have this:

 //some code
 private int[] data = new int[3];
 //some code

Then in my constructor:

Answer 1

You could either do:

public class Data {
    private int[] data;

    public Data() {
        data = new int[]{0, 0, 0};
    }
}

Which initializes data in the constructor, or:

public class Data {
    private int[] data = new int[]{0, 0, 0};

    public Data() {
        // data already initialised
    }
}

Which initializes data before the code in the constructor is executed.
