Question

I’m a bit mixed up. Here is my work so far.

public class CourseYear
{
    private String courseName;
    private int year;
    private String tutorName;
    private String [] moduleList;

The moduleList is to hold 6 modules

public CourseYear()
{
    courseName = "Default";
    year = 0;
    tutorName = "Joe Bloggs";
    moduleList = new String [5];
}

This is where my problem lies, I’m not sure how to do the array parts:

public void addModule(Module newModule, int index)
{
    Module = newModule[0];
    Module = newModule[1];
    Module = newModule[2];
    Module = newModule[3];
    Module = newModule[4];
    Module = newModule[5];
}

I have no idea how to do the get methods

public Module getModule(int index)
{
    return Module[index];
}

Answer 1

you need to reference your array with the index. In your class definition you need a

private Module[] modules = new Module[6]; // initialize

If you want your Array to contain Module instances, the array needs to be an array of Modules. Right now your class has a String array.

and then your add method becomes

public void addModule(Module newModule, int index){
    this.modules[index] = newModule; // put the instance in the correct bucket
}

Note a few things:

1). Your array has 6 buckets, so the indexes allowed are 0-5. If index in the addModule method is out of bounds you will get an exception.

2). addModule expects newModule to be a module instance. So you use addModule like

CourseYear courseYear = new CourseYear(); // create a courseyear
courseYear.addModule(new Module(), 0); // create a module and add it at index 0
courseYear.addModule(new Module(), 1); // create a module and add it at index 1
...

You can also use addModule inside the CourseYear class. Say you want to initialize in your constructor

public CourseYear(){
    this.addModule(new Module(), 0); // create a module and add it at index 0
    this.addModule(new Module(), 1); // create a module and add it at index 1
    ...
}

You should be able to figure out getModule
