JavaDoc for JSpinner contains errors

XMLWordPrintable

        A DESCRIPTION OF THE PROBLEM :
        There are three typos in the example given at the top.
        1. Remove the second left brace in the " catch ... " line.
        2. Terminate " JComponent editor = spinner.getEditor() " with a semicolon.
        3. A closing parenthesis is missing before the semicolon in
         " ((DefaultEditor)editor).getTextField().setValue(spinner.getValue(); "

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        try {
               spinner.commitEdit();
           }
           catch (ParseException pe) {
               // Edited value is invalid, spinner.getValue() will return
               // the last valid value, you could revert the spinner to show that:
               JComponent editor = spinner.getEditor();
               if (editor instanceof DefaultEditor) {
                   ((DefaultEditor)editor).getTextField().setValue(spinner.getValue());
               }
               // reset the value to some known value:
               spinner.setValue(fallbackValue);
               // or treat the last valid value as the current, in which
               // case you don't need to do anything.
           }
           return spinner.getValue();
        ACTUAL -
        See above.
