4,308 PointsNow add a second constructor that takes a String parameter. Use this parameter to update mType to a specific type of spa
I'm stuck here. Please help!
public class Spaceship {
public String mType = "ROCKET";
public Spaceship (String type, Rocket) {
mType = "ROCKET";
}
public Spaceship () {
mType = "SHUTTLE";
}
public String getType() {
return mType;
}
public void setType(String type) {
mType = type;
}
}

23,309 PointsYou you are a bit off here. Let me try to explain inside code example.
TASK 1 - create a constructor that takes 0 arguments and sets mType to SHUTTLE.
//You set mType to SHUTTLE, in the first no arg constructor. This is so that if I call an instance of this class to create an object, //and I don't give it any params. it will auto default and create an object of a spaceship called SHUTTLE.
//This is the class and I create a variable mType. That's it. No value or anything. Like so below:
public class Spaceship {
public String mType;
}
// first no arg constructor. I set mType = to SHUTTLE. So when I do 'Spaceship X = new Spaceship();' I get a spaceship with the //name of SHUTTLE. Like so below.
public Spaceship () {
mType = "SHUTTLE";
}
public String getType() {
return mType;
}
public void setType(String type) {
mType = type;
}
}
EXERCISE TWO
Now add a second constructor that takes a String parameter. Use this parameter to update mType to a specific type of spa
// Create a variable for mType, Check!
public class Spaceship {
public String mType;
//Create first no arg constructor so if I pass in no values when creating the object it gets called SHUTTLE by default
public Spaceship() {
mType = "SHUTTLE";
}
//Add a second constructor. So if I don't want a default value of SHUTTLE. I can do 'Spaceship X = new Spaceship("ROCKET");'
// Now because of the method signature. It will not call the no arg constructor, it will call the constructor that matches //arguments passed in. Then set mType to whatever is passed in. I created the variable but did not define it at the
//class level so it would be available to set in different methods so scope isn't an issue. It's not static or final so I don't have
// to set it right off the bat. This comes into play more so when member variables are private but out of the scope of the
//question lol
public Spaceship(String type) {
mType = type;
}
public String getType() {
return mType;
}
public void setType(String type) {
mType = type;
}
}
I hope that helps, let me know if you have any other questions I can try to clear up.
Thanks!
