'StringBuilder' can be replaced with 'String'
Reports usages of 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 performance drawback on modern JVMs. In many cases, String
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;
