Affects PMD Version:
6
Rule:
LawOfDemeter
Description:
PMD's application of the Law of Demeter considers it a violation to query the standard name of the Java UTF-8 character set. Unless the character set is assigned to an explicit variable name first.
Code Sample demonstrating the issue:
public final class Fib {
/** utility class */
private Fib() {}
public static void main(final String[] args) throws IOException {
System.out.print("N = ");
try (Scanner scanner = new Scanner(System.in, StandardCharsets.UTF_8.name())) {
final int n = scanner.nextInt();
System.out.println(String.format("Fib %d = %d", n, fib(n)));
}
}
}
As a workaround, I am disabling this rule in my rulesets.xml:
<rule ref="category/java/design.xml">
<exclude name="LawOfDemeter" />
</rule>
