StringBuffer
, StringBuilder
, or StringJoiner
which can be replaced with a single String
concatenation.
Using String
concatenation
makes the code shorter and simpler.
This inspection only reports when the suggested replacement does not result in significant

concatenation may perform better.
Example:
StringBuilder result = new StringBuilder(); result.append("i = "); result.append(i); result.append(";"); return result.toString();
After the quick-fix is applied:
String result = "i = " + i + ";"; return result;
