'size() == 0' can be replaced with 'isEmpty()'
Reports .size() or .length() comparisons with a 0 literal that can be replaced with a call to .isEmpty().
Example:
boolean emptyList = list.size() == 0;After the quick-fix is applied:
boolean emptyList = list.isEmpty();- By ID
Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.
SizeReplaceableByIsEmpty
Use the Ignored classes table to add classes for which any .size() or .length() comparisons should not be replaced.
Use the Ignore expressions which would be replaced with !isEmpty() option to ignore any expressions which would be replaced with !isEmpty().
Here you can find the description of settings available for the 'size() == 0' can be replaced with 'isEmpty()' inspection, and the reference of their default values.
You can suppress this inspection by placing the following comment marker before the code fragment where you no longer want messages from this inspection to appear:
//noinspection SizeReplaceableByIsEmptynote
Actual comment syntax will depend on the code language you are working with
