Quartz scheduler with excluding specific time range

I want to schedule through Quartz scheduler excluding specific time ranges.

Ex : 2am - 3am and 5:30pm - 5:45pm

Is there any other way to achieve this without the use cron expression and cron scheduler?

This is what Quartz Calendars are used for. Since in your case you want to exclude specific daytime ranges, you will want to use the DailyCalendar.

A single DailyCalendar can exclude a single day time range. Since you want to exclude multiple (two) ranges, you will need to combine two DailyCalendars like so:

// calendar that excludes the 2am-3am day time range
DailyCalendar dc1 = new DailyCalendar(2,0,0,0,3,0,0,0);

// calendar that excludes the 5:30pm-5:45pm day time range
DailyCalendar dc2 = new DailyCalendar(17,30,0,0,17,45,0,0);

// combine the two calendars so that both ranges are excluded by dc2
dc2.setBaseCalendar(dc1);

// register the calendar with the scheduler
scheduler.addCalendar("MyExcludedDayTimeRangesCalendar", dc2, true, true);

MutableTrigger trigger = ... create SimpleTrigger / CronTrigger  / DailyTimeInterval / CalendarIntervalTrigger instance

// associate the created trigger with the registered calendar - the trigger will exclude calendar's time ranges  
trigger.setCalendarName("MyExcludedDayTimeRangesCalendar");

...
