Question is:

Define two date variables and assign the dates as 10/19/18 and 11/20/18 (format mm/dd/yy), and print the number of days between the dates.

class Example{
      static void main(String[] args){
       String date = "10/19/18"
        Date d1=Date.parse('MM/dd/yy',date)
       //complete the code

      }
}

please, anyone, help me to solve this, and i bit confused with the Date.parse() method. because it takes an only a single parameter, but in the question, it has given two parameters. so kindly explain how to do it.

What I have tried:

I have tried, but I was not getting the logic of differentiating between of given two dates of the days to display

I am using TimeCategory class to get the time difference in my groovy script but it throws error,

groovy.lang.MissingMethodException: No signature of method: org.codehaus.groovy.jsr223.GroovyScriptEngineImpl.use() is applicable for argument types: (java.lang.Class, Script17$_run_closure2) values: [class groovy.time.TimeCategory, Script17$_run_closure2@362b384c]\nPossible solutions: use(java.lang.Class, groovy.lang.Closure), use(java.util.List, groovy.lang.Closure), use([Ljava.lang.Object;), dump(), grep(), any()"}

 

This is my snapshot of script below,

use(TimeCategory) {
def duration = StartDate - CurrentDate
// logger.info("RECEIVED VALUES : days = {}, .hours = {}, minutes = {}, seconds = {}", ${duration.days}, ${duration.hours}, ${duration.minutes},${duration.seconds})
def DaystoHours = (duration.days*24)
def DaystoHourstoMins = (DaystoHours*60)

def HourstoMins = (duration.hours*60)

def SecstoMins = (duration.seconds/60)

def TotalMins = DaystoHourstoMins+HourstoMins+duration.minutes+SecstoMins

WAIT_PERIOD_2 = "PT"+TotalMins+"M"
}

Reference: Calculate days between two dates | Level Up Lunch[^]

Java

//Difference in days
@Test
public void difference_between_date_in_days() {

    def today = new Date()
    def yesterday = today - 1

    assert 1 == today.minus(yesterday)
    assert 1 == today - yesterday
}

Another way[^], using TimeCategory[^] for getting a duration:

JavaScript

use(groovy.time.TimeCategory) {
   def duration = date1 - date2
   println "days: ${duration.days}, Hours: ${duration.hours}"
}
