title: Take an attribute from a list of pojo class to an array of that attribute
body: <p>Suppose for one field/attribute in a pojo class , i need to create a list of that field's value alone. Its doable in java using iteration . But is there any custom library for doing this ?
  For eg :</p>
  
  <pre><code>public class User
  {
    private String name;
    private Integer age;
    // setters and getters. 
  }
  </code></pre>
  
  <p>What i want is , <code>List&lt;User&gt;</code> ---> <code>List&lt;String&gt;</code> , here the values are of field "name".</p>
