Switch statement using a String type

Question

I'm trying to switch a string type value which I have made static. However I can't figure out how to put this into a switch statement I was previously using an 'if else' statement but due to the number of items I want to switch this doesn't work.

For the if else I was using `

if (item.ActivityFeedType.equals("Comment"))

for switch I;m trying to use

case (item.ActivityFeedType.equals("Comment")):

Is there something I'm missing?

Answer 1

1. switch for Strings exists, but it's only available starting from Java 7. The syntax actually is just as with an Integer switch:

   String test = "test";
   switch (test) { 
       case "testt": 
           System.out.println("Wrong"); 
           break; 
       case "test": 
           System.out.println("Got it"); 
           break; 
   }
   

2. There is no situation that a switch can handle, but a simple if-else could not. A switch simply is more convenient.

3. I'd recommend selecting lower-case starting letters for a Class' attributes.

Thouhg if you are working with Java 1.7,
Java's switch-case allows only constant variable in case.
