Having compiler issues with Array, can anyone help please?

Question

Using your Invoice class created in lab02, write a client program that allows the user to input three Invoice objects into an array of Invoice objects. After you have inputted all of the invoices, print a heading and then output all of the array elements (Invoice objects) by calling the method from your Invoice class that displays all of the data members on a single line using uniform field widths to insure that all Invoice objects will line up in column format (created in Lab04). At the end of the loop, display the calculated total retail value of all products entered in the proper currency format.
Example of possible program execution:
Part Number : WIDGET
Part Description : A fictitious product
Quantity : 100
Price          : 19.95
(etc.)
Example of possible output
Part Number          Part Description          Quantity          Price     Amount
WIDGET          A fictitious product     100          19.95     199.95
Hammer               9 pounds          10          5.00     50.00
(etc.)
Total Retail Value:                                   249.95
This is what I have so far at the bottom, can anyone tell me what I'm doin wrong please
//Invoice Lab 6
//Application to test class Invoice with arrays
public class InvoiceTest
public static void main( String args[] )
Invoice invoice1 = new Invoice( "1234", "Hammer", 2, 14.95 );
Invoice array [] = new Invoice [2];
array [0] = new Invoice ("1234", "Hammer", 2, 14.95);
array [1] = new Invoice ("5678", "PaintBrush", -5, -9.99);
double total = 0.0;
System.out.println("Part Number                    Description               Quantity          Price               Amount");
System.out.println("----------------------------------------------------------------------------------");
for (int i=0; <=2; i++)
total+=array.getPaymentAmount();
     system.out.println("The Total retail value is: %.2f\n")
// display invoice1

Change this (check my comments):
for (int i=0; <=2; i++) // what is <=2??  check the fixed version
total+=array.getPaymentAmount(); //two things 1) this needs to be inside the for-loop 2) you need to tell the array which index to look at
system.out.println("The Total retail value is: %.2f\n") //no need for \n because println does it automagically
}to this:
for(int i=0; i<array.length; i++) {
    total += array.getPaymentAmount();
System.out.println("The total retail value is: " + total); //if you need another blank line like above be my guest
Honestly, I didn't look past this part so fix this and post again if something is still broken.
