Question

Im having issues now with static and non staic errors. with sertain variables unable to find the main method.

I have strated the program by creating a seperate file which instantiates the class. like so:

public class StartUp {
    public void main(String[] args) {
        MainDriver theMainDriver = new MainDriver();
        theMainDriver.start();
    }
}

Within certain classes in the program it passes variables back to the mainDriver. But when I try to refrence it to, I get the error “cannot find symbol variable theMainDriver” .

e.g:

 public void getEmployee()  {
      theMainDriver.setEmployee(theEmployee);
 }

 public void getEmployeeID() {
     theMainDriver.setEmployeeID( randomIDno);
 }

how can I declare the main Driver in a way that makes it more visible to other classes.
It does find the main driver if I do this MainDriver.setEmployeeID( randomIDno); but then it has issues with non static method cannot be referenced from a static context.

You can do the following:

public class StartUp {

    public static MainDriver theMainDriver;

    public void main(String[] args) {
        theMainDriver = new MainDriver();
        theMainDriver.start();
    }
}

And call from any class as follows:

Startup.theMainDriver.setEmployeeID(randomIDno);
