Write java method to take two integer arrays and one int size variables as parameters and check if sum of both array are same or not

please use java language requirement- The code expected to be relatively short, up to 10 lines

How can I express the following situation in Java programming?   Orcs, Hobbits, and Tom Bombadil We have n-1 Orcs and n Hobbits who want to cross a river. We also have Tom Bombadil who wants to cross as well. Only Hobbits and Tom Bombadil can row the boat (don’t ask　me why!) At all times, the number of Hobbits on either side of the river must be greater or equal the number of Orcs on that side (unless there are no Hobbits on that side), or the Hobbits will be killed by the Orcs! If the boat holds 2, with n=4 or more, the problem has no solution. If the boat can hold 3, then up to n=5 can be solved. If the boat can hold 4, any number (n) Hobbits can cross. So -- if n = 1,2 or 3 - use a boat of size 2. If n = 4 or 5 - use a boat of size 3. If n > 5 use a boat of size 4. If n <0 invalid input if n = 0 no output.

Keeping data structures and algorithms in mind, can you help me to write these two functions in java? The factorial of a positive integer n —which we denote as n!—is the product of n and the factorial of n − 1. The factorial of 0 is 1. Write two different recursive methods that each return the factorial of n. Include the two methods in a file called Test.java   What to submit: The Test.java
