2. Programming Task For this lab, we are asking you to create a parameterized class called Utility and decide on its methods' signature. Class Utility is a class that contains 4 methods. The implementation of the methods is given below. The only thing that you need to do is to decide on the correct method signature so that all the test cases are passed. - linearSearch is a method that linearly searches for the given item {i.e. the input parameter) in list. The list is an instance variable of class Utility. You should decide on what is the correct method signature when the implementation looks like below: int position = 1; for (int i = a; i (); for (T obj: list) this.list.add(obj); return true; } else return false; - removeZero is a method that does not work on the instance variable of this class. It gets a list and removes all the zeros from the list. Here is the implementation of the method: for (int i = a; i
