String concatenation

Last modified: 03 December 2024

Reports String concatenations. Concatenation might be incorrect in an internationalized environment and could be replaced by usages of java.text.MessageFormat or similar classes.

Example:

String getMessage(String string, int number) {
  return string + number;
}
