Use string in switch case in java

Question

I need to change the following if's to a switch-case while checking for a String, to improve the cyclomatic complexity.

String value = some methodx; if ("apple".equals(value)) {     method1; }  if ("carrot".equals(value)) {     method2; }  if ("mango".equals(value)) {     method3; }  if ("orange".equals(value)) {     method4; } 

But I am not sure what value I'm going to get.

Java (before version 7) does not support String in switch/case. But you can achieve the desired result by using an enum.

private enum Fruit {     apple, carrot, mango, orange; }  String value; // assume input Fruit fruit = Fruit.valueOf(value); // surround with try/catch  switch(fruit) {     case apple:         method1;         break;     case carrot:         method2;         break;     // etc... }
