Statement can be replaced with 'assert' or 'Objects.requireNonNull'
Reports if
statements that throw only java.lang.Throwable
from a then
branch and do not have an else
branch. Such statements can be converted to more compact assert
statements.
The inspection also reports Guava's Preconditions.checkNotNull()
. They can be replaced with a Objects.requireNonNull()
call for which a library may not be needed.
Example:
if (x == 2) throw new RuntimeException("fail");
if (y == null) throw new AssertionError();
Preconditions.checkNotNull(z, "z");
After the quick-fix is applied:
assert x != 2 : "fail";
Objects.requireNonNull(y);
Objects.requireNonNull(z, "z");
- 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.
IfCanBeAssertion
By default, this inspection provides a quick-fix in the editor without code highlighting.
This inspection depends on the Java feature 'Assertions', which is available since Java 1.4.
