public class MainActivity extends ActionBarActivity {

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

        TextView cal = (TextView)findViewById(R.id.cal);
        
        Calendar calendar = Calendar.getInstance(); 
        SimpleDateFormat format1 = new SimpleDateFormat("dd-MM-yyyy");
        SimpleDateFormat format2 = new SimpleDateFormat("yy/MM/dd");

        SimpleDateFormat format5 = new SimpleDateFormat("hh:mm a");
        SimpleDateFormat format6 = new SimpleDateFormat("HH:mm");

        cal.setText(
         format1.format(calendar.getTime()) + "\n" +
         format2.format(calendar.getTime()) + "\n" +
         format3.format(calendar.getTime()) + "\n" +
