import java.util.Calendar;

import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;
import android.os.Bundle;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        
        TextView tim = (TextView)findViewById(R.id.tim);
        TextView cal = (TextView)findViewById(R.id.cal);
        
        tim.setText(
         "currentTimeMillis: " + System.currentTimeMillis() + "\n" +
         "nanoTime" + System.nanoTime() + "\n"
         );
        
        Calendar calendar = Calendar.getInstance(); 
        cal.setText(
         "YEAR: " + calendar.get(Calendar.YEAR) + "\n" +
         "MONTH: " + calendar.get(Calendar.MONTH) + "\n" +
         "DAY_OF_MONTH: " + calendar.get(Calendar.DAY_OF_MONTH) + "\n" +
         "HOUR_OF_DAY: " + calendar.get(Calendar.HOUR_OF_DAY) + "\n" +
         "MINUTE: " + calendar.get(Calendar.MINUTE) + "\n" +
         "SECOND: " + calendar.get(Calendar.SECOND) + "\n"
         );

    }
