    Default Switch statement using a String with Java 1.7

    Hi,

    switch(name) //Where name is a String
    {
    Code block
    }

    I am trying to use a String switch statement like the one just above. I am getting the following error:

    Error: Cannot switch on a value of type java.lang.String. Only convertible int values or enum constants are permitted.

    After some research, a String can only be used in a switch statement in Java 1.7. I do have the most up to date version of Java 1.7 (checked on the java website) and I am still getting that error. Does anyone know why and how I can fix it?

    Additional info: Compiler is Eclipse Compiler 0A48 with Dr. Java.

    Thank you.

    From the wording of the error message it seems eclipse believes you wish to use an older version of java for that project.
    I have encountered this error before and that was the cause of the issue for me. There is a way to tell eclipse to use a specific version by default, and a way to set the version per project. Unfortunately I do not remember how to make the change. Not much of an eclipse guy yet..

    Perhaps some poking around on your own or with a search engine will help you determine if that is your problem or not.

    Right-click on your project and Open the project properties.

    Then on the left menu, select Java Compiler. This will list the project-specific JDK compliance version that project is using.
