Groovy Question

Convert associative arrays to map in Groovy

I have two

with identical lengths. They are "associative arrays" in the sense that the string values of one are the keys and the string values in the other are the values:

String[] keys = { 'fizz', 'buzz', 'bupo' }
String[] values = { 'true', 'false', 'yes' }

I want to take these two associative arrays and convert them into a
with some Groovy magic. So far I have tried the following but it is not working:

Map<String,String> kvPairs = [keys, values]

Any ideas where I'm going awry?


You can do it like this:

String[] keys = [ "fizz", "buzz", "bupo" ] as String[]
String[] vals = [ "true", "false", "yes" ] as String[]
Map<String, String> kvPairs = [ keys, vals ].transpose()​.collectEntries()​


[fizz:true, buzz:false, bupo:yes]
