Exception Handling

 /// Exception Handling : The execution of the program is terminated abnormally

/// DifferedLoadException : Thrown when a deferred library fails to load
/// FromatException : The exception is thrown when a string or some other data does not have an expected format
/// and can't be processed
/// IntegerDivisionByZeroException : The exception is thrown when a number is divided by zero
/// IOException : Base class for all Input-Output related exceptions
/// IsolateSpawnException : Thrown when an isolate can not be created
/// OSError : An Exception holding information about an error from the operating system
/// TimeoutException : Thrown when a scheduled timeout happens while waiting for an async result

//void main() {
  // try {
  //   int x = 5 ~/ 0;
  //   print(x);
  // } on IntegerDivisionByZeroException {
  //   print("Can not divide by zero");
  // };

  /// catch clause :
  /// when we don't know about the exception then use the catch clause
  /// We can spacify one or two parameters to catch(). The first is the "exception object" that was thrown,
  /// and the second is the "StackTrace object".
  // try {
  //   int x = 5 ~/ 0;
  //   print("$x");
  // }
  // catch(e) { // Here, "e" is exception object
  //   print("Exception : $e");
  // }

  // try {
  //   int y = 5 ~/ 0;
  //   print("$y");
  // }
  // //Here, "e" is exception object, "s" is StackTrace object
  // catch(e, s) {
  //   print("Exception : $e");
  //   print(s);
  // }

  /// Finally clause : To ensure that some code runs whether or not an exception is thrown, use a finally clause
  /// To ensure the execution of program, finally clause is used
  // try {
  //   int z = 5 ~/ 0;
  //   print("$z");
  // } catch(e) {
  //   //print("Exception : $e");
  // } finally {
  //   print("finally clause...");
  // }

//}
