Question

I have a little problem here.

I am declaring a new object “Fleet” in these methods:

public void run() throws FileNotFoundException
{
    File file = new File(getFile());
    Fleet fleet = new Fleet(file);
    buildFleet(file, fleet);
    }

private void buildFleet(File file, Fleet fleet) throws FileNotFoundException
{
    fleet.addVehicle(Honda);
    userMenu(fleet);

}

The last line calls the userMenu() method. In this method I need to be able to change the value of “File” inside Fleet without creating a new instance of the class.

private void userMenu(Fleet fleet) throws FileNotFoundException
{
    PrintWriter pw = new PrintWriter("temp.txt");
    File file = new File("temp.txt");
    fleet = new Fleet(file);

    this.createMenu();
    choice = this.menu.getChoice();


while(choice != 8)
{
    switch(choice)
    {
    case 1:
        //Do stuff
        fleet.addVehicle(Honda);
        break;
    }
}

Also, I am not allowed to create any new class level data.
Any suggestions?

Solved:

I changed:

private void userMenu() throws FileNotFoundException
{
    PrintWriter pw = new PrintWriter("temp.txt");
    File file = new File("temp.txt");

to:

private void userMenu(Fleet fleet) throws FileNotFoundException
{
    PrintWriter pw = new PrintWriter("temp.txt");
    File file = new File("temp.txt");
    fleet.file = file;
