Storing borrow objects in a file. Take the Loan class as a starting point from listing 10.2 in the textbook, this is attached. Write about the class to implement Serializeable interface. Write about the program in listing 10.1 TestLoanClass.java (attached) as follows: The program must: Load loan objects from file at startup, if there is a file with such. All read loan objects are stored in an ArrayList or equivalent. Information about read-in loan objects is printed, print out the total loan amount and monthly payment. New loan objects can be created Write loan objects, all or a selection, to file if the user wants this. Tips: When loading objects from a file, use EOFException to stop loading, if you do not know the number to be read.
