How to properly manage and respond to checked exceptions in code?

In Java, checked exceptions require mandatory handling or declaration in the method signature with throws. To properly manage such exceptions:

• Handle exceptions where they can be correctly processed — for example, log the error, properly terminate the operation, or notify the user.
• Use try-catch blocks to catch exceptions:

  try {
      // code that may throw an exception
  } catch (IOException e) {
      // handle the exception
  }
  

• If the method cannot handle the exception, declare it with throws to pass the responsibility to the calling code.
• Do not suppress exceptions without reason — always try to either handle or explicitly pass them on.

This approach ensures reliability and predictability of the program's operation, allowing correct response to errors during execution.
