title: Exception handling Try-Catch block difference
body: <p>I know, we can use try-catch block to handle exceptions. But I have some doubts in the usage of Try-Catch.
  What is the difference between</p>
  
  <pre><code>   try
     {
        //Some code
     }
     catch
     {
  
     }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>   try
     {
      //Some code
     }
     catch(Exception)
     {
  
     }
  </code></pre>
  
  <p>and</p>
  
  <pre><code>   try
     {
      //Some code
     }
     catch(Exception oops)
     {
  
     }
  </code></pre>
  
  <p>In my program, I need to catch all exceptions and I don't want to log them. From the above mentioned Try-Catch blocks, which should be used?</p>
