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

Your constructor needs to call the constructor of the superclass. If the superclass had defined a no-argument constructor, you would not be seeing this error. To expand on the other answers with some code, what you need is

 public DenseBoard(Tile t[][]){
      //You need a way to figure meaningful values to the superconstructor here
      super(intVar1, intVar2);
      Board myBoard = new DenseBoard(t.length, t[0].length); //I think 
     //this now becomes unnecessary?
  }

Or alternatively modify your Board class to include

public Board()
{
...
}
