It's slightly more efficient to append single characters to ``++StringBuffer++`` and ``++StringBuilder++`` instances as ``++char++``s, than as ``++String++``s. That is, it's more efficient to put a single ``++char++`` in single quotes, rather than double quotes.
== Noncompliant Code Example
[source,java]
----
StringBuilder sb = new StringBuilder();
sb.append("a"); // Noncompliant
----
== Compliant Solution
[source,java]
----
StringBuilder sb = new StringBuilder();
sb.append('a'); // Noncompliant
