title: Simplies way to get value from Class List to String List
body: <p>I try to get value for each <code>TestClass</code> object in List to new String List.</p>
  
  <p>For example:</p>
  
  <pre><code>public class TestClass {
  
       private String testValue;
  
       // setter and getter
  }
  </code></pre>
  
  <p>And now in different class I do it like that :</p>
  
  <pre><code>List&lt;TestClass&gt; testClassList = getTestClassList();
  
  List&lt;String&gt; testStringList = new ArrayList&lt;String&gt;();
  
  for( TestClass testClass : testClassList ) {
       testStringList.add(testClass.getTestValue());
  }
  
  return testStringList;
  </code></pre>
  
  <p>And I wonder is there any simplest way to do this?</p>
