&&

I'm not sure what you mean by 'checked exceptions' but if you remove the word 'checked' then yes. The purpose of a try-catch block is to react to code that may throw an exception.

try {
        // Some code that throws an exception
        // Note that if an exception *is* thrown at some point
        // it doesn't execute any more code from this block
 
} catch (NameOfTheException) {
       // Do something when this type of exception is thrown
 
} catch (Exception) {
       // Exception is the superclass of all exceptions.  
       // You can even create your own exceptions by extending this class 
       // and then throw it where appropriate
 
} finally {
      // This happens weather an exception is thrown or not.
 
 
}
