Different formatters use different formatting symbols, and it can be easy to confuse one for the other. But get it wrong, and your output may be useless.


This rule logs an issue when the wrong type of format string is used for Guava, slf4j, logback or ``++MessageFormat++`` strings.


== Noncompliant Code Example

----
String message = MessageFormat.format("Now is the %s %d all good people", "time", 4);  // Noncompliant
----


== Compliant Solution

----
String message = MessageFormat.format("Now is the {1} {2} all good people", "time", 4);  // Noncompliant
----
