Extra Credits Array Madness

So I set up some code like this, guessing I'm wrong since I get mad compile errors. Is it that I'm providing incorrect parameters for SetText?

public class TextViewArrayMadness extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_text_view_array_madness);

    String[] arrays = {"1","2","3","4","5"};

    TextView window1 = (TextView)findViewById(R.id.textView);
    TextView window2 = (TextView)findViewById(R.id.textView2);



    window1.setText(arrays[1] + arrays[2]+ arrays[3]+ arrays[4]+ arrays[5]);
    window2.setText(arrays[5] + arrays[4]+ arrays[3]+ arrays[2]+ arrays[1]);

}

When you're accessing the values in arrays, remember that the index starts at 0. So arrays[0] would be the string "1", arrays[1] would be "2", and so on. You are trying to access arrays[5] which is not valid. There is no string at index 5 within arrays.
