else if (today 02:01 until today 14:00) then display yyy
else if (today 14:01 until today 20:00) then display zzz

If you had Date objects for each of the times and used its get time method to retrieve number of milliseconds, you could easily compare those values.
If you are using java 1.8 look at the java.time package for some useful classes/methods.

Hi Norn, sorry that I new to Java, can you explain how to do the compare? I found there is java.time as well.

how to do the compare

The times I was talking about are contained in a long variable. The compares would be between two numeric values that represent the milliseconds since the EPOCH time.

I write as below, but it seems not working
Can you help me check what is wrong on the code?

Calendar calendar = Calendar.getInstance();
int hrs = ( calendar.get( Calendar.HOUR_OF_DAY ) + 8 );
int minute = calendar.get( Calendar.MINUTE );

TimsSpan time01 = new TimeSpan(01, 0, 0);
if (( hrs > 20 && minute > 00 ) && ( hrs < 02 && minute < 01 )) {
then xxx;
} else if (( hrs > 2 && minute > 00 ) && ( hrs < 14 && minute < 01 )) {
then yyy;
} else if (( hrs > 14 && minute > 00 ) && ( hrs < 20 && minute < 01 )) {
then zzz;
}

Can you post a small, complete program that compiles, executes and shows the problem?
Add some print statements that shows what the code is doing and what the values are it is testing.

Be sure to wrap the code in code tags to preserve formatting.

I think you are not able to provide any help on this.. thanks anyway.. I getting help from other place.

Good luck.
It is not possible to help you with the bits and pieces of unformatted code you posted. There needs to be something that will compile and execute for testing.

Be sure to post the solution you find here in case others have the same problem.
