Sanity4J was created to simplify running multiple static code
analysis tools on the Java projects. It provides a single entry
point to run all the selected tools and produce a consolidated
report, which presents all findings in an easily accessible
manner.
ConfusingTernary
ConfusingTernary
Avoid negation within an “if” expression with an “else” clause. For example, rephrase:
if (x != y) diff(); else same(); as: if (x == y) same(); else diff();
Most “if (x != y)” cases without an “else” are often return cases, so consistent use of this rule makes the code easier to read. Also, this resolves trivial ordering problems, such as “does the error case go first?” or “does the common case go first?”.
This rule is defined by the following Java class: net.sourceforge.pmd.lang.java.rule.design.ConfusingTernaryRule
Example(s):
boolean bar(int x, int y) {
return (x != y) ? diff : same;
}
