Replace all occurrences Check this option to automatically replace all the occurrences of the selected expression (if the selected expression is found more than once in the class).

  • This field is only available if the project is configured to use annotations, that is, the library annotation.jar is added to the project or module. If annotations are not available, this option does not appear in the dialog.
  • The project language level should be 5.0 to support annotations.
