Since Java 7, ``++String++``s can be used as ``++switch++`` arguments. So when a single ``++String++`` is tested against three or more values in an ``++if++``/``++else if++`` structure, it should be converted to a switch instead for greater readability.


*Note* that this rule is automatically disabled when the project's ``++sonar.java.source++`` is lower than ``++7++``.


== Noncompliant Code Example

----
if ("red".equals(choice)) {  // Noncompliant
  dispenseRed();
} else if ("blue".equals(choice)) {
  dispenseBlue();
} else if ("yellow".equals(choice)) {
  dispenseYellow();
} else {
  promptUser();
}
----


== Compliant Solution

----
switch(choice) {
  case "Red":
    dispenseRed();
    break;
  case "Blue": 
    dispenseBlue():
    break;
  case "Yellow":
    dispenseYellow();
    break;
  default:
    promptUser();
    break;
}
