title: Java 8 - What is the real time usecase for return method from another method?
body: <p>As we know , Java 8 supports functional programming.</p>
  
  <p>We can pass method as a parameter and return a method from another method.</p>
  
  <p>I know , call back is one of the real time usecase for passing method as parameter . But I couldn't find any real usecase for returning method from another method . Please give me some real time example for this.</p>
