title: Updating a List of Object from another list of object using java stream
body: <p>I have a list of Object A</p>
  
  <pre><code>A{
  name
  age
  dob
  }
  </code></pre>
  
  <p>and list of Object B</p>
  
  <pre><code>B{
  name
  dob
  }
  </code></pre>
  
  <p>.</p>
  
  <p>I always get the List of A with A.dob as null. and List of B with B.dob having value. 
  I need to loop thru List of A and List of B find the common objects using the name field in each A and B object and  update A.dob using B.dob </p>
  
  <p>Can this be done using streams?</p>
