title: Methods that throw an exception that do not require catching
body: <p>Sorry if this is a very basic question</p>
  
  <p>As for my understanding if you have a method that throws an exception, you are required to catch it (or throw it) whenever you will be using that method.</p>
  
  <p>However some methods that throw an exception do not require me to catch it like:</p>
  
  <pre><code>int num = Long.parseInt(sampleString);
  </code></pre>
  
  <p>Can anybody shed some light please?</p>
