enum type declaration error

I came from C domain and learning JAVA.
I believe, there is C equivalent "enum" type existed in JAVA. But my
initial experiment is giving compile error as below. Please help me to
understand where I made mistake. Note that, I am using the latest GCC
compiler for JAVA (gcj).

Thanks in advance.

Compile error:
/*****
myHelloWorld.java:8: error: Invalid declaration.
       public enum returnStatus {RETURN_TRUE, RETURN_FALSE}
                                ^
myHelloWorld.java:8: confused by earlier errors, bailing out

*****/

My experimental code is as below:
/*
 myHelloWorld.java
 */
public class myHelloWorld
{

    // Return value definition (public)
    public enum returnStatus {RETURN_TRUE, RETURN_FALSE}

    // Private method to print something on the console
    private returnStatus printSomething()
    {
    // Return status intialization
           returnStatus retValue = new returnStatus;

        // Print something on the console
        System.out.println("Hi Hello World !");

        //Return
          retValue = retValue.RETURN_TRUE;
          return retValue;

    }//printSomething()

    // Main method
    public static void main(String[] args)
    {
       printSomething();

    }//main()
}//myHelloWorld class
