Question

Background:

I’m creating a basic download centre on a concurrent server.

I create file objects in the Server class under a main method

File[] files = {
    new File("1. Program", "myProgram.jar"),
    new File("2. Image", "myPicture.jpg"),
    new File("3. Book", "myBook.txt")};

This references to the File class where I create constructors and getters.

class File {

    private String option;
    private String fileName;


    public File(String option, String fileName) {
        this.option = option;
        this.fileName= fileName;
    }

    public String getOption() {
        return option;
    }


    public String getFileName() {
        return fileName;
    }

    public void getFileOptions(File[] files) {
        for (File f : files) {
            System.out.printf("The option is %s\n", f.getOption());
        }
    } 
}

I am attempting to call the getFileOptions method from my ServerState class.

theOutput= File.getFileOptions(files);

The output is a string that is returned to a client.

My IDE says that (files) cannot be found. Any ideas where I’m going wrong? Cam I not return results to a class where the object wasn’t initially created?

Answer 1

OK so I have moved the File objects into the ServerState class and access the options using String theOutput = files[0].toString() + files[1].toString() + files[2].toString(); by calling a toString() method from the File class that also contain the object constructors, getters and setters.
