Adding a default constructor with no parameters

I'm really struggling with this question.

First, add a default constructor without parameters. Inside the constructor, set ship Type to "SHUTTLE".

Spaceship.java 
public class Spaceship {
    public String shipType;

    public String getShipType() {
      return shipType;
    }

    public void setShipType(String shipType) {
      shipType = "Shuttle";
    }
}

Hi Andre,

A constructor is a method that takes the name of the class and is public. It returns an instance of the class but that doesn't need adding to the method signature.

In this case we want it to have no parameters and set a value of shipType to SHUTTLE.

So, create a method called the same as the class and make it public:

public Spaceship(){

}

Inside the method set shipType to SHUTTLE:

public Spaceship(){
  shipType = "SHUTTLE";
}

I hope that makes sense.

Steve.
