[SOLVED] change a list of day , month and year to DATE in java

change a list of day , month and year to DATE in java

i have these lists

   def day   =[1,1,1,1,1,1,1,1,1,1,1,1,1]
   def month =[10,9,8,7,6,5,4,3,2,1,12,11]
   def year  =[2011,2011,2010,2011,2011,2012,2011]

Now i want to do some thing like this for the whole list in a kind of for loop

          def date= new Date(year,month,day)

How can i do this

Thanks

Solution

Try not to use separate collections when the data is tightly-coupled (better yet to use an object).

dateNums = [
    [1, 10, 2011],
    [1, 9, 2011],
    // etc.
]
dates = []

dateNums.each {
    d = new Date(it[2]-1900, it[1]-1, it[0])
    println d
    dates.add(d)
}

Note that the Date(year, month, date) is deprecated, and you should likely use the Date construction methods I linked to in your previous question.

d = new Date().parse('MM/dd/yyyy', "${it[0]}/${it[1]}/${it[2]}")

Better still, skip the intermediate steps.

def getDate(month, day, year) {
    new Date().parse('MM/dd/yyyy', "${month}/${day}/${year}")
}

dates = [
    getDate(1, 10, 2011),
    getDate(1, 9, 2011)
]

dates.each { println it }
