Can someone explain his last line of code?

public class MainActivity extends Activity {
    private EditText mNameField;
    private Button mStartButton;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mNameField = (EditText) findViewById(R.id.nameEditText);
        mStartButton = (Button) findViewById(R.id.startButton);

        mStartButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String name = mNameField.getText().toString();
                Toast.makeText(MainActivity.this,"Welcome " + name ,Toast.LENGTH_LONG).show();
                startStory(name);
            }
        });
    }
    private void startStory(String name){
        Intent intent = new Intent(this, StoryActivity.class);
        intent.putExtra("name",name);
        startActivity(intent);
    }
}
