Since Checkstyle 3.1
Detects inline conditionals. Here is one example of an inline conditional:
String a = getParameter("a"); String b = (a==null || a.length()<1) ? null : a.substring(1);
Rationale: Some developers find inline conditionals hard to read, so their employer's coding standards forbid them.
To configure the check:
<module name="Checker"> <module name="TreeWalker"> <module name="AvoidInlineConditionals"/> </module> </module>
Example:
int x = 5; boolean foobar = (x == 5); // OK String text; text = (text == null) ? "" : text; // violation String b; if (a != null && a.length() >= 1) { // OK b = a.substring(1); } else { b = null; } b = (a != null && a.length() >= 1) ? a.substring(1) : null; // violation
All messages can be customized if the default message doesn't suit you. Please see the documentation to learn how to.
