title: When to catch the Exception vs When to throw the Exceptions?
body: <p>I have been coding in Java for a while now. But sometimes, I don't understand when I should throw the exception and when should I catch the exception. I am working on a project in which there are lot of methods. The hierarchy is something like this-</p>
  
  <pre><code>Method A will call Method B and Method B will call some Method C and Method C will call Method D and Method E.
  </code></pre>
  
  <p>So currently what I am doing is- I am throwing exceptions in all the methods and catching it in Method A and then logging as an error.</p>
  
  <p>But I am not sure whether this will be the right way to do it? Or should I start catching exceptions in all the Methods. So that is why this confusion started in my- When should I catch the Exception vs When should I throw the exceptions. I know it's a silly question but somehow I am struggling to understand this major concept.</p>
  
  <p>Can someone give me a detailed example of <code>When to catch the Exception vs When to throw the Exceptions</code> so that my concepts gets cleared on this? And in my case, should I keep on throwing the exception and then catch it in the main calling Method A?</p>
