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

why not simply

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

the reason you got the error is because int[] data = ... declares a new variable and hides the field data

however it should be noted that the contents of the array are already initialized to 0 (the default value of int)
