Java
New object is compared using '=='
Warning
New
Last modified: 03 December 2024 Reports code that applies ==
or !=
to a newly allocated object instead of calling equals()
.
The references to newly allocated objects cannot point at existing objects, thus the comparison will always evaluate to false
. The inspection may also report newly created objects returned from simple methods.
Example:
void test(Object obj) {
if (new Object() == obj) {...}
}
After the quick-fix is applied:
void test(Object obj) {
if (new Object().equals(obj)) {...}
}
- 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.
