I can't figure this out! Please help!

I am taking my first java class so I am not very good at this. My problem is that I can't figure out how to make part of my code work. Everything works but this part. I know it is wrong, but I have no idea how else to do it. I feel bad e-mailing my teacher on the weekend, so if you guys help me I would really appreciate it. Thank you very much!

HTML Code:

                System.out.println("Do you want trees to be delivered? \n"
                                                                +"1 for Yes\t"
                                                                + "0 for No");
                                                               

                forDelivery = keyboard.nextInt();

               
                if(forDelivery == 1)
                  {
                        (singleTree < 5) &&  (deliveryCost== 10.00) // this is the area that I have
                        (singleTree >=5) && (deliveryCost==50.00)// no clue how to write properly
                System.out.println("There will be a delivery charge according to how many trees you ordered.");

        else if (forDelivery == 0)
                        {
        System.out.println("In-Store Pickup will be available after 4 PM");
                        }
               

                        }

Say what the problem is: ie what happens when you run the code, and what you expect or want to happen.

Also it may be a good idea to clean up the format of the code. Remove any distracting left hand indents if they are common to all the lines. And have the { and } pairs line up (with any nested pairs also lining up, but with more indent.)

Please explain the problem and expected result?
