Create Map from existing Map in Groovy - groovy

Question

I have a Map
[email:[hus#gmail.com, vin#gmail.com], jobTitle:[SE, SD], isLaptopRequired:[on, on], phone:[9908899876, 7765666543], name:[hus, Vin]]
for which i need to have a another Map like
[hus:[hus#gmail.com,SE,99087665343],vin:[vin#gmail.com,SE,7765666543]]
How can do it in Groovy?

Answer 1

You could do it like:
def map = [email:['hus#gmail.com', 'vin#gmail.com'], jobTitle:['SE', 'SD'], isLaptopRequired:['on', 'on'], phone:['9908899876', '7765666543'], name:['hus', 'Vin']]
def result = [:]
map.name.eachWithIndex { name, idx ->
result << [ (name): map.values()*.getAt( idx ) - name ]
}
assert result == [hus:['hus#gmail.com', 'SE', 'on', '9908899876'], Vin:['vin#gmail.com', 'SD', 'on', '7765666543']]
Or, you could also do:
def result = [map.name,map.findAll { it.key != 'name' }.values().toList().transpose()].transpose().collectEntries()
But this is just less code at the expense of both readability and resource usage ;-)

Answer 2

The most visual solution i have:
def map = [email:['hus#gmail.com', 'vin#gmail.com'], jobTitle:['SE', 'SD'], isLaptopRequired:['on', 'on'], phone:['9908899876', '7765666543'], name:['hus', 'Vin']]
def names = map.name
def emails = map.email
def jobTitles = map.jobTitle
def isLaptopRequireds = map.isLaptopRequired //sorry for the variable name
def phones = map.phone
def result = [:]
for(i in 0..names.size()-1) {
result << [(names[i]): [emails[i], jobTitles[i], isLaptopRequireds[i], phones[i]]]
}
assert result == [hus:['hus#gmail.com', 'SE', 'on', '9908899876'], Vin:['vin#gmail.com', 'SD', 'on', '7765666543']]
}
