Error Handling

  • An error that arises through mistakes in coding or through incorrect data that is entered by the user is called an “exception”
  • Such errors that are encountered while a program runs are said to be “thrown”
  • Programmers try to anticipate these errors and either prevent them or solve them before they happen
  • Java uses the “Try... Catch...” process in order to try running a block of code to test for errors and then catch an error if it occurs
