Reports throws
clauses with exceptions that are more generic than the
exceptions that the method actually throws.
Example:
public void createFile() throws Exception { // warning: 'throws Exception' is too broad, masking exception 'IOException'
File file = new File("pathToFile");
file.createNewFile();
}
After the quick-fix is applied:
public void createFile() throws IOException {
File file = new File("pathToFile");
file.createNewFile();
}
Configure the inspection:
- Use the Maximum number of hidden exceptions to warn field to ignore exceptions, that hide a larger number of other exceptions than specified.
- Use the Only warn on RuntimeException, Exception, Error or Throwable option to have this inspection warn only on the most generic
exceptions.
- Use the Ignore exceptions declared on methods overriding a library method option to ignore overly broad
throws
clauses
in methods that override a library method.
- Use the Ignore exceptions which hide others but are themselves thrown option to ignore any exceptions that hide other exceptions
but still may be thrown from the method body and thus
are technically not overly broad.
