title: Is there a convention for modifying the naming of identifiers that would otherwise be keywords in Java?
body: <p>For example, you might do something like this:</p>
  
  <pre><code>public final class Library {
      public void checkOut(Book book) { /* banana banana banana */ }
      public void return_(Book book) { /* banana banana banana */ }
  }
  </code></pre>
  
  <p>but is there an actual convention that Java programmers should follow?</p>
