import android.text.format.Time;
import android.widget.TextView;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;

public class MainActivity extends AppCompatActivity {

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

        TextView hour12txt = (TextView)findViewById(R.id.hour12);

        TextView hour24txt = (TextView)findViewById(R.id.hour24);

        TextView minutetxt = (TextView)findViewById(R.id.minute);

        TextView secondtxt = (TextView)findViewById(R.id.second);

        TextView millisecondtxt = (TextView)findViewById(R.id.millisecond);

        TextView ampmtxt = (TextView)findViewById(R.id.ampm);

        TextView yeartxt = (TextView)findViewById(R.id.year);

        TextView monthtxt = (TextView)findViewById(R.id.month);

        TextView weektxt = (TextView)findViewById(R.id.week);

        TextView daytxt = (TextView)findViewById(R.id.day);


        Calendar Time = Calendar.getInstance();

        int millisecond = Time.get(Calendar.MILLISECOND);
        int second = Time.get(Calendar.SECOND);
        int minute = Time.get(Calendar.MINUTE);
        int hour24 = Time.get(Calendar.HOUR_OF_DAY);
        int hour12 = Time.get(Calendar.HOUR);
        int ampm = Time.get(Calendar.AM_PM);


        hour24txt.setText(hour24+"(24hr format)");
        hour12txt.setText(hour12+"(12hr format)");
        minutetxt.setText(""+minute);
        secondtxt.setText(""+second);
        millisecondtxt.setText(""+millisecond);

        if(ampm==0){
            ampmtxt.setText("AM");
        }else{
            ampmtxt.setText("PM");
        }



        Calendar Date = Calendar.getInstance();

        int dayofyear = Date.get(Calendar.DAY_OF_YEAR);
        int year = Date.get(Calendar.YEAR);
        int week = Date.get(Calendar.WEEK_OF_MONTH);
        int month = Date.get(Calendar.MONTH);
        int day = Date.get(Calendar.DAY_OF_MONTH);

        monthtxt.setText(""+month);
        weektxt.setText(""+week);
        yeartxt.setText(""+year);
        daytxt.setText(""+day);
    }
}
