How to add age to ageList =[12,13,23]

Question

may be too simple groovy question but....please help

i have a list like this:

def ageList =[12,13,23]

i want to get this:

def newAgeList =[age:12,age:13,age:23]

could some one help me out?

thank you so much!

Answer 1

Does this work for you?

def newAgeList = ageList.inject([:]) { map, item -> if (!map['age']) map['age'] = []; map['age'] << item; map }

his would result in: ['age':[12, 13, 23]]

Otherwise, you can get the literal value as something like:

def newAgeList = ageList.collect { "age:$it" }

his would result in: ['age:12', 'age:13', 'age:23']

A third option:

def newAgeList = ageList.collect { ['age':it] }

This would result in: [['age':12], ['age':13], ['age':23]]

Unfortunately, you can't do this as a map like you showed above as map keys must be unique.

Really it all depends on what you are trying to do with the result.

Answer 2

Don't know if this is possible since you want to use the same map key 'age' for three different values. You'll end up overwriting the existing value with a new value.
