Computing Program

I need to write a program in java with the following description and am struggling greatly and this seems so simplistic....A cancellation error occurs when you are manipulating a very large number with a very small number. The large number may cancel out the smaller number. To avoid cancellation errors and obtain more accurate results, carefully select the order of computation. For example from left to right or right to left. Write a program to compare the summation of the preceding series, computing from left to right and from right to left with n=50000 use the following fback, ffront, fback-ffront, d back, dfront, dback-dfront ## Deliverables Source code ## Deadline information Help me fast its due 9-17 by 930 est
