I’m learing JAVA programming language.
I’m creating a method GetResult with an argument Integer.
When Java try to compile, there are more errors.

Please help me to understand where is the error.
Thank you

public String GetResult(int numero){
    String TestVal;
         switch(nome){
            case 1:
            case 2:
            case 3:
                    TestVal= "bad job";
                        break;
            case 4:
            case 5:
            case 6:
                    TestVal= "enough job";
                        break;
             case 7:
             case 8:
             case 9:
                     TestVal= "good job";
                        break;
         }

    return TestVal;
}

I tried changing modifiers.
