In this assignment you will create several methods, each doing some specific task. You only need to edit the Main.java file, which has some dummy$/$stub boilerplate code already in place. The code can be compiled, but the results are not correct. You need to fix each method so it does what it's supposed to$,$ according to the following description:

Method sum$(...)$ that expects two integers, and returns the sum of the expected integers.

Method difference$(...)$ that expects two integers, and returns the difference between the expected integers.

Method division$(...)$ that expects two integers, and returns the first number divided by the second $($hint: pay attention to the types of the variables involved!$).$

Method multiplication$(...)$ that expects two integers, and returns their values multiplied.

Method remainder$(...)$ that expects two integers, and returns the remainder of the division of the first number by the second.

Method isOdd$(...)$ that expects one integer, and returns true if the given value is odd, false otherwise.

Method isEven$(...)$ that expects one integer, and returns true if the given value is even, false otherwise.

Method lowest$(...)$ that expects an array of integers and returns the lowest value inside the given array.

Method highest$(...)$ that expects an array of integers and returns the highest value inside the given array.

Method average$(...)$ that expects an array of integers and returns the average of the values inside the given array.

Method reversed$(...)$ that expects an array of integers and returns a new array in reversed order.

Method determinant$(...)$ that expects a $2-$D array of integers that represents a $2$ by $2$ matrix, and returns the determinant of that matrix.

Boilerplate code:
