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.<

Answer 1

Everybody is using at least Java 7 now, right? Here is the answer to the original problem:

String myString = getFruitString();

switch (myString) {

    case "apple":
        method1();
        break;

    case "carrot":
        method2();
        break;

    case "mango":
        method3();
        break;

    case "orange":
        method4();
        break;
}

Notes

• The case statements are equivalent to using String.equals.
• As usual, String matching is case sensitive.
• According to the docs, this is generally faster than using chained if-else statements (as in cHao's answer).
