Problem with Compiler Spaceship Question

I've been stuck here for the whole day trying to figure out what's wrong. It keeps saying compiler error and I'm stuck at task one 1.

LandingActivity.java

import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;

public class LandingActivity extends AppCompatActivity {

    public Button thrustButton;
    public TextView typeLabel;
    public EditText passengersField;

    public Spaceship spaceship;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_landing);

        thrustButton = (Button)findViewById(R.id.thrustButton);
        typeLabel = (TextView)findViewById(R.id.typeTextView);
        passengersField = (EditText)findViewById(R.id.passengersEditText);

        // Add your code here!
        spaceship = new Spaceship("FIREFLY");
        typeLabel.setText(spaceship.getShipType());
        passengersField.setText(spaceship.getNumPassengers() + "");

    }
}

Spaceship.java

public class Spaceship {
    private String shipType;
    private int numPassengers = 0;

    public String getShipType() {
      return shipType;
    }

    public void setShipType(String shipType) {
      this.shipType = shipType;
    }

    public int getNumPassengers() {
      return numPassengers;
    }

    public void setNumPassengers(int numPassengers) {
      this.numPassengers = numPassengers;
    }

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

    public Spaceship(String shipType) {
      this.shipType = shipType;
    }
    public Spaceship(String type) { //<----You have to type a String inside the method
      mType = type;
    }
}

You're getting a error because you have two constructors that take the same argument types (called the signature in Java) and the compiler can't distinguish between the two. (The constructors that take a single String argument). Also the 2nd on the two is referring to a field that doesn't exist. I'd say that the first version is correct and it should be fine if you remove the other.

I cleared my browser cache and it worked. But thanks anyways for you helpful answer.
