issues when Iterate Map with list as value using groovy -

def map  = new hashmap<string,list<string>>()  def list = new arraylist<string>() def list1 = new arraylist<string>() list.add("hello1") list​.add("world1") list.add("sample1") list.add("sample1")​​​​​​​​​​​​​​​​​​​​​​​​ list1.add("hello2") list1.add("world2") list1.add("sample2") list1.add("sample2") map.put("abc",list) map.put("bcd",list1) def data = new arraylist<string>() for(e in map){ println "key = ${e.key} value=${e.value}" // data = "${e.value} string[]" data = "${e.value}" println "size ${data.size()} " --(b)  check(data) ​} def check(input) { println "${input.size()}" ---(a) for(item in input){ print "$item  "​​​​​​​​​​​​​​​​​} ​}​ 

i have pass string[] java function groovy script. trying read array list , convert string array. problem when assign {e.value} variable data , try size data.size() (both step (a) , (b) ). , size 34. counting each character not word whole list. want iterate on each word list. kindly let me know how resolve problem.

sample output

key = abc value=[hello1, world1, sample1, sample1]  size 34 

here groovified vesion of creating map , accessing it:

def map = [abc:['hello1', 'world1','sample1', 'sample1'], bcd:['hello2', 'world2','sample2', 'sample2']] map.collect{ println "key: ${it.key}, list: ${it.value}, , size: ${it.value.size()}" } 

output:

key: abc, list: [hello1, world1, sample1, sample1], , size: 4 key: bcd, list: [hello2, world2, sample2, sample2], , size: 4 

if want convert list array can it:

def list = ['hello1', 'world1','sample1', 'sample1'] assert list instanceof list def array = list string[] assert array instanceof string[] assert !(array instanceof list)
