通过 groovy 中的键列表从 map 获取值

Question

I have a list of strings, i would like to get values from a map, using this list of keys.

For example:

ListOfKeys = ["one", "two", "three"]
map =["one":1,"two":2,"three":3,"four":4]

I should get only the first three because they are in the map, the rest are not.

Thanks

Answer 1

ListOfKeys = ["one", "two", "three"]
map =["one":1,"two":2,"three":3,"four":4]

def values = ListOfKeys.collectEntries{ map[it] }

Answer 2

ListOfKeys = ["one", "two", "three"];
map =["one":1,"two":2,"three":3,"four":4];

result = ListOfKeys.collectEntries{[it,map[it]]}

println result
