Converting from int to string?

I can't figure out how to convert mSpaceship.getNumPassengers from int to a string type. I read a previous answer that said to use +"", but I can't figure out the how to use the syntax?

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

public class LandingActivity extends Activity {

    public Button mThrustButton;
    public TextView mTypeLabel;
    public EditText mPassengersField;

    public Spaceship mSpaceship;

    public void onCreate(Bundle savedInstanceState) {

        mThrustButton = (Button)findViewById(R.id.thrustButton);
        mTypeLabel = (TextView)findViewById(R.id.typeTextView);
        mPassengersField = (EditText)findViewById(R.id.passengersEditText);

        // Add your code here!
      mSpaceship = new Spaceship("FIREFLY");
public class Spaceship {
    private String mType;
    private int mNumPassengers = 0;

    public String getType() {
      return mType;

    public void setType(String type) {
      mType = type;

    public int getNumPassengers() {
      return mNumPassengers;

    public void setNumPassengers(int numPassengers) {
      mNumPassengers = numPassengers;

    public Spaceship() {
      mType = "SHUTTLE";

    public Spaceship(String type) {
      mType = type;

int mainInt = 123456789; // Type 1 String string1 = "" + mainInt; // Type 2 String string2 = "123"; // Type 3 String string3 = Integer.toString(mainInt); // Type 4 String string4 = String.valueOf(mainInt); // Type 5 String string5 = String.format("%d", mainInt); // Type 6 StringBuilder sb = new StringBuilder(); sb.append(mainInt); String string6 = sb.toString();

////////////////////////////// In your's case ////////////////////// mPassengersField.setText(mSpaceship.getNumPassengers()+""); ///////////////////////////// OR ///////////////////////////////////// mPassengersField.setText(""+mSpaceship.getNumPassengers());

Good Luck
