'String.equals()' can be replaced with 'String.isEmpty()'
Reports equals()
being called to compare a String
with an empty string. In this case, using .isEmpty()
is better as it shows you exactly what you're checking.
Example:
After the quick-fix is applied:
Locating this inspection
- 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.
StringEqualsEmptyString- Via Settings dialog
Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.
"".equals(str)
returns false when str
is null. For safety, this inspection's quick-fix inserts an explicit null-check when the equals()
argument is nullable. Use the option to make the inspection ignore such cases.
