I am trying to get package name but i get an error

Error: incompatible types:NameExpr cannot be converted String

String packagePrefix = cu.getPackage().getName();

I tried to convert "getPackage().getName()" to string with toString() method following code:

String packagePrefix = cu.getPackage().getName().toString();

And i get following error:

Error:cannot find symbol:method.toString()
location:class NameExpr

Probably NameExpr class doesn't contain toString() method depending on this question:What does a "Cannot find symbol" compilation error mean? How can i fix this problem?

Edit: Full Code:

 public static String parseClassname(File filename) throws Exception {
        try (FileInputStream fin = new FileInputStream(filename)) {
            CompilationUnit cu = JavaParser.parse(fin);
            String packagePrefix = cu.getPackage().getName().toString();
            if (!packagePrefix.isEmpty()) packagePrefix += ".";

            for (TypeDeclaration type : cu.getTypes())
            {
                if (type instanceof ClassOrInterfaceDeclaration) 
                return packagePrefix + type.getName();    

            }
        }
        return null;
    }

What is cu in your code? – Thiyagu Mar 08 '18 at 10:45
it means there is something wrong, it can't find the toString() method, but since that's inherited from Object .. – Stultuske Mar 08 '18 at 10:45

It would be really helpful if you'd provide a [mcve] here. – Jon Skeet Mar 08 '18 at 10:45
check the type returned by getName() – Stultuske Mar 08 '18 at 10:47
getName returned NameExpr and i cannot convert this name to string.I expected to getPackage().getName() return a package name(string) and it didn't return string – my-lord Mar 08 '18 at 11:05
