Must explicitly invoke another constructor

Question

Why is Eclipse keeps giving me error on the constructor:

 public DenseBoard(Tile t[][]){
      Board myBoard = new DenseBoard(t.length, t[0].length);
  }
         


        

Answer 1

Just to point out

public DenseBoard(Tile t[][]) {
    Board myBoard = new DenseBoard(t.length, t[0].length);
}

myBoard is local variable, you will not be able to refer it when you create a new object using new DenseBoard(Tile t[][]).

You can do it in 2 ways.

public DenseBoard(Tile t[][]) {
    super(t.length, t[0].length); // calling super class constructor
}

// or
// I would prefer this
public DenseBoard(Tile t[][]) {
    this(t.length, t[0].length); // calling DenseBoard(int rows, int cols) constuctor, which is internally passing the value to super class.
}
