I have time in below format
2015-10-28T18:37:04.899+05:30
I have to create slots in below format
11.00AM - 12.00PM 28/10/15
12.00PM - 1.00PM 28/10/15
1.00PM - 2.00PM 28/10/15
String timeValue = "2015-10-28T18:37:04.899+05:30";
StringTokenizer stringTokenizer = new StringTokenizer(timeValue,"T");
String dateValue = stringTokenizer.nextElement().toString();
String endDateValue = "2015-10-30";
String restString= stringTokenizer.nextElement().toString();
StringTokenizer secondTokeniser = new StringTokenizer(restString,":");
String hours = secondTokeniser.nextElement().toString();
String minutes = secondTokeniser.nextElement().toString();
hours = String.valueOf(Integer.parseInt(hours) + 2);
if (Integer.parseInt(minutes) > 30){
minutes = "00";
}else{
minutes = "30";
}
String amOrPm = null;
if(Integer.parseInt(hours) < 12){
amOrPm = "AM";
}else{
amOrPm = "PM";
hours = String.valueOf(getHoursValue(Integer.parseInt(hours)));
}
String time1 = hours + ":" + minutes + " " + amOrPm;
String time2 = "12" + ":" + "00" + " AM ";
String format = "yyyy-mm-dd hh:mm a";
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
Date dateObj1 = sdf.parse(dateValue + " " + time1);
Date dateObj2 = sdf.parse(endDateValue + " " + time2);
Logger.d(TAG, "Date Start: " + dateObj1);
Logger.d(TAG, "Date End: " + dateObj2);
long dif = dateObj1.getTime();
while (dif < dateObj2.getTime()) {
Date slot = new Date(dif);
Log.d(TAG, "Hour slot = " + slot);
dif += 1800000;
}
}catch (ParseException ex){
ex.printStackTrace();
}
By the above code I am getting below output
Wed Jan 28 20:00:00 IST 2015

1.00PM - 2.00PM 28/10/15
Can any one please help me regarding this
You can use the following, please note that for month you shoud use MM instead of mm. I add a simple getHoursValue since I don't know yours.
Hope this helps!
public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
displayTimeSlots();
}
private int getHoursValue(int hours){
return hours - 12;
}
private void displayTimeSlots(){
String timeValue = "2015-10-28T18:37:04.899+05:30";
StringTokenizer stringTokenizer = new StringTokenizer(timeValue,"T");
String dateValue = stringTokenizer.nextElement().toString();
String endDateValue = "2015-10-30";
String restString= stringTokenizer.nextElement().toString();
StringTokenizer secondTokeniser = new StringTokenizer(restString,":");
String hours = secondTokeniser.nextElement().toString();
String minutes = secondTokeniser.nextElement().toString();
hours = String.valueOf(Integer.parseInt(hours) + 2);
if (Integer.parseInt(minutes) > 30){
minutes = "00";
}else{
minutes = "30";
}
String amOrPm;
if(Integer.parseInt(hours) < 12){
amOrPm = "AM";
}else{
amOrPm = "PM";
hours = String.valueOf(getHoursValue(Integer.parseInt(hours)));
}
String time1 = hours + ":" + minutes + " " + amOrPm;
String time2 = "12" + ":" + "00" + " AM ";
String format = "yyyy-MM-dd hh:mm a";
SimpleDateFormat sdf = new SimpleDateFormat(format);
try {
Date dateObj1 = sdf.parse(dateValue + " " + time1);
Date dateObj2 = sdf.parse(endDateValue + " " + time2);
Log.d("TAG", "Date Start: " + dateObj1);
Log.d("TAG", "Date End: " + dateObj2);
long dif = dateObj1.getTime();
while (dif < dateObj2.getTime()) {
Date slot1 = new Date(dif);
dif += 3600000;
Date slot2 = new Date(dif);
dif += 3600000;
SimpleDateFormat sdf1 = new SimpleDateFormat("hh:mm a");
SimpleDateFormat sdf2 = new SimpleDateFormat("hh:mm a, dd/MM/yy");
Log.d("TAG", "Hour slot = " + sdf1.format(slot1) + " - " + sdf2.format(slot2));
}
}catch (ParseException ex){
ex.printStackTrace();
}
}
}
Here is the logcat:
