How to convert list of maps to list of objects

I have a POJO class like as below :-

public class Pojo {
   String param1
   List param2
   Map param3
   Boolean param4
   Integer param5
}

I have a List which contains Map objects with the same structure as like Pojo :-

List list = [
        [param1: "a", param2: ["a","b","c"], param3:[a:"a",b:"b",c:"c"], param4:true, param5:1],
        [param1: "b", param2: ["d","e","f"], param3:[d:"d",e:"e",f:"f"], param4:false, param5:2]
]

Now I want to convert this list of maps to list of pojo objects

Anyone have idea how to convert it??

It's a one-liner....

// here's the class we want to convert to 
public class Pojo {
   String param1
   List param2
   Map param3
   Boolean param4
   Integer param5
}

// here the data we want to convert
List list = [
        [param1: "a", param2: ["a","b","c"], param3:[a:"a",b:"b",c:"c"], param4:true, param5:1],
        [param1: "b", param2: ["d","e","f"], param3:[d:"d",e:"e",f:"f"], param4:false, param5:2]
]

// this is the conversion
List<Pojo> pojos = list.collect { new Pojo(it) }
