I need some help with this program:
/* PF2 lab4 In this lab, you will practice working with onedimensional arrays. Design and implement a BigInteger class thatcan add, subtract and multiply integers up to 25 digits. To helpyou get started, I have provided you with methods to input andoutput the numbers. You merely have to implement the add, subtractand multiply methods. SIMPLIFYING ASSUMPTION: Don’t worry aboutnegative numbers. When subtracting numbers, the difference willalways be positive. But your program should be able to subtract,for instance, 5 from 1001. (has to handle “borrowing”) Put your labin ~/PF2/lab4/Lab4.java */
This is what I have so
