[SalesForce] how to get the date and time format that you want in apex

I have these lines of codes in my test class:

Test.startTest();        
    String sch = '0 0 23 * * ?';         
    String jobId = System.schedule('Delete Batch Donation Logs', sch, batchDeleteLogs);
    CronTrigger ct = [SELECT Id, CronExpression, TimesTriggered, NextFireTime FROM CronTrigger WHERE id = :jobId]; 
    System.assertEquals(0, ct.TimesTriggered); 
    System.assertEquals(date.today()+' '+ '23:00:00', String.valueOf(ct.NextFireTime));
    Test.stopTest();

the date format that I need is the year-month-day only (2018-07-25) without time. how can I achieve that?

You can use the format method of the DateTime Class. It outputs the date in the desired format.

Example:

System.now().format('yyyy-MM-dd')

Optionally, for you example, you can compare actual DateTimes without converting to string

System.assertEquals(DateTime.newInstance(System.today(), Time.newInstance(23, 0, 0 , 0)), ct.NextFireTime);

You can also use Period object here to get the quarter start and end date.

List<Period> Dates = [Select type, StartDate, EndDate 
                       From Period WHERE type = 'Quarter' 
                        AND StartDate = THIS_FISCAL_QUARTER];
Date StartDateQuarter = Dates[0].StartDate;
Date EndDateQuarter = Dates[0].EndDate;

try like this now use

StartDateQuarter and EndDateQuarter in query
AND ( createdDate>=: quarterstartdate AND createdDate>=: quarterenddate )

[SalesForce] Validate Date Format – Apex

You can try casting the user input into a date and return a custom error if it is not a valid date string.

String input = '2019-04-08';

try {
   Date d = Date.valueOf(input);
}
catch(TypeException e) {
   // Throw a custom exception and handle the message in your component
}
