Assertion can be replaced with 'if' statement

Last modified: 03 December 2024

Reports assert statements and suggests replacing them with if statements that throw java.lang.AssertionError.

Example:

assert param != null;

After the quick-fix is applied:

if (param == null) throw new AssertionError();
