Question

在Groovy中，如何从以下内容中提取新列表：

   def people = [ 
           new Person(name:"Tom", yearOfBirth:1985),
           new Person(name:"Abigail", yearOfBirth:1987),
           new Person(name:"Joyce", yearOfBirth:1984),
           new Person(name:"James", yearOfBirth:1987),
           new Person(name:"Scott", yearOfBirth:1985),
           new Person(name:"Ruth", yearOfBirth:1984)
       ]  

   class Person {
       String name
       int yearOfBirth
   }

这样新列表如下所示：

 ["Tom", "Abigail", "Joyce", "James", "Scott", "Ruth"]
