Groovy- count all nulls in an array

I want to print  how many nulls, 1's and 2's seperately. Json : {"prods": [{"Item":13,"rate":200, "Ids": []}, {"Item":13,"rate":200, "Ids": []},  {"Item":11,"rate": 100, "Ids": [ {"level": 1}]},  ...

Hi SK07,

 

Dont think of it to be complex. If you only wanna count the number of "[]", try

// your list aa=[[], [], [1,1],[2,2,2]]
def num = 0
for(item in aa){
    if(item.size() < 1) num++
}
log.info "[Ids []: $num]"

 

Regards,
