title: adding elements in a list to another list
body: <p>First I have two strings.</p>
  
  <pre><code>String name = "my name is";
  String address = "my address is";
  </code></pre>
  
  <p>Then I want to split the 'name' string value from the space character and add to a list.</p>
  
  <pre><code>List word_list = new ArrayList();
  word_list.add(Arrays.asList(name.split(" ")));
  </code></pre>
  
  <p>Then similarly I want to split the 'address' string value and add to the same 'word_list'.</p>
  
  <pre><code>word_list.add(Arrays.asList(address.split(" ")));
  </code></pre>
  
  <p>From this finally what I get is,</p>
  
  <pre><code>[[my, name, is],  [my, address, is]]
  </code></pre>
  
  <p>But what I want is,</p>
  
  <pre><code>[my, name, is, my, address, is]
  </code></pre>
  
  <p>Is there any shorter method other than writing a loop to solve this problem?</p>
