title: What is Round brackets / parentheses () in try catch in Java
body: <p>As per as my knowledge we use <code>try catch</code> as follows:</p>
  
  <pre><code>try {
     //Some code that may generate exception
  }
  catch(Exception ex) {
  }
     //handle exception
  finally {
     //close any open resources etc.
  }
  </code></pre>
  
  <p>But in a code I found following</p>
  
  <pre><code>try(
      ByteArrayOutputStream byteArrayStreamResponse  = new ByteArrayOutputStream();                   
      HSLFSlideShow   pptSlideShow = new HSLFSlideShow(
                                        new HSLFSlideShowImpl(
   Thread.currentThread().getContextClassLoader()
         .getResourceAsStream(Constants.PPT_TEMPLATE_FILE_NAME)
                                       ));
   ){
  }
  catch (Exception ex) {
         //handel exception
  }
  finally {
        //close any open resource
  }
  </code></pre>
  
  <p>I am not able to understand why this parentheses <code>()</code> just after try. </p>
  
  <p>What is the usage of it? Is it new in Java 1.7? What kind of syntax I can write there?</p>
  
  <p>Please also refer me some API documents.</p>
