here is a text file containing the details of several invoices details. Each invoice uses 3 lines of the file. The first of the three lines is a string giving the date of the invoice, for example “1/5/2021” or “2/6/2021”. The second of the three lines contains double giving the amount, the third line is boolean indicating whether it is paid or not. However, the very first line of the file is an integer number, which says how many invoices are given in the file in the lines which follow it (i.e. how many records will follow). Text file example for two vehicles “invoices.txt” 2 1/5/2021 50.0 true 2/6/2021 20.0 false Write code for a method named processTextFile() which will open the file named ‘invoices.txt’, from which it will read the data of invoices. It will create Invoice objects using this data by calling the constructor that takes the parameters (date, amount, paid) , placing them into an ArrayList invoiceList.
