Accessing hour,minute and second using Calendar class

Question

I am trying to set an alarm on a particular day and time.So setting hour and minute using Calendar.But when i try to access the hour which is set in Calendar using cal.set,i get a different value than that was set by me manually.

Code

Calendar cal=Calendar.getInstance();
cal.set(Calendar.HOUR,7);
cal.set(Calendar.MINUTE,30);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
Toast.makeText(getApplicationContext(), "Alarm worked. "+cal.HOUR+cal.MINUTE,cal.SECOND Toast.LENGTH_LONG).show();

Result i want

Alarm worked. 7:30:0

What i get now

Alarm worked. 10:12:13

P.S

1.I found many posts which deal with Calendar issues but couldn't find my solution.

2.The result what i am getting i.e 10:12:13 is not my current time(current date,current minute,current second) either.So i don't know why and from where these data are coming.

3.I tried using HOUR_OF_DAY instead of HOUR but nothing useful.

Solution

Toast.makeText(getApplicationContext(), "Alarm worked. "+cal.get(Calendar.HOUR)+" "+cal.get(Calendar.MINUTE)+" "+cal.get(Calendar.SECOND), Toast.LENGTH_LONG).show();

This worked because Calendar.HOUR,Calendar.MINUTE are constants.See the answer of @PopoFibo to get the clear picture.

Please see the Original post.It shows `Alarm worked. 10:12:13 ` — Sash_KP, Jan 31 '14 at 10:57

Date s = cal.getTime();
SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss a");
String t = sdf.format(s);
Toast.makeText(this, t, Toast.LENGTH_SHORT).show();

The problem is in your Toast, you are printing the constants of the Calendar class:

Calendar.HOUR = 10
Calendar.MINUTE = 12
Calendar.SECOND = 13

Instead, get the value at their respective indexes - like for HOUR it would be cal.get(Calendar.HOUR)

System.out.println(cal.get(Calendar.HOUR) + ":" + cal.get(Calendar.MINUTE) + ":" + cal.get(Calendar.SECOND));

Would give (correct output):

7:30:0

And, System.out.println(Calendar.HOUR + ":" + Calendar.MINUTE + ":" + Calendar.SECOND);

Would give (incorrect output):

10:12:13

can you try with:

Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 7);
calendar.set(Calendar.MINUTE, 30);

and then toast it

add these lines before setting time..

                Cal.set(Calendar.MONTH , month);
                Cal.set(Calendar.YEAR, year);
                Cal.set(Calendar.DAY_OF_MONTH,day);
