Please do in java and put comments as im trying to understand what does what. thank you!

This assignment asks you to write a collection of little functions that all operate on a class of array of integers. The main function for testing is given below. Use the main from below. Do not make changes to the main except for substituting first name with your first name. Implement a class called arrIntFirstName, 1. Class has only one private variable in the class which is an array of ints, called arr. 2. Implement a constructor that takes the length as argument and create the array arr using new of that length, but does not fill it. (See 2, below, for how to fill it.) 3. Implement a second constructor that takes an array of ints as an argument and uses it to initialize the arr of the class (kind of like a setter). The kind of copying to use here is called a "shallow copy". 4. Create a function called arrDisplayFirstName O that prints the array to the console in a form that looks exactly like the literal strings used below for initialization of test arrays in main. The literal starts with a " " ", then lists the numbers separated by commas but no spaces, and ending with " } ". The output must even work if the length of the array is 0 (" \{\} ) or 1 (no commas). In the arrInt class, only the displayArrFirstName O method should include calls to sysout. 5. Create a function called arr TotFirstName that returns the total of the values in the array. 6. Create a function called arrMaxFirstName that returns the maximum value in the array. 7. Create a function called arrayMinFirstName that returns the minimum value in the array. a. When looking for min or max, compare each new value to the min or max value that you have seen so far. Do not initialize that value to an arbitrary extreme (like 0 ). Observe that when you check the first value of the array, that value should become the min or max you have seen so far, since you haven't seen anything else. Assuming that you are using a variable called minSeen, the correct solution is to initialize minSeen to the first value right away, before starting the loop. That way you don't have to know anything about the range of possible values (which could be all negative, making 0a bad choice for the initial value.) b. If the Array is empty, The arrayMin and arrayMax 1. Create a function called arrayMinfirstName that returns the minimum value in the array. a. When looking for min or max, compare each new value to the min or max value that you have seen so far. Do not initialize that value to an arbitrary extreme (like 0 ). Observe that when you check the first value of the array, that value should become the min or max you have seen so far, since you haven't seen anything else. Assuming that you are using a variable called minSeen, the correct solution is to initialize minSeen to the first value right away, before starting the loop. That way you don't have to know anything about the range of possible values (which could be all negative, making 0 a bad choice for the initial value.) b. If the Array is empty, The arrayMin and arrayMax methods should just return 0 . 8. Create a function called arrRangeFirstName that returns the range of the values in the array. In math, the range is the magnitude of the difference between the minimum and maximum (inclusive). You compute it by subtracting the minimum from the maximum. You already have methods that return the min and max. Use them and do not include any loops in this method. 9. Create a function called arrAverageFirstName 0 that returns the average value in the array. Even though the array contains ints, return the average as a double. Note that you have a method for the sum, and you can get the length by using the array property of the array itself. So this method only has to do a divide. Test that you can get a result that includes a fractional part (not just whole numbers). a. In the average and range functions, use the arrTotFirstName, arrMinFirstName, and arrMaxFirstName functions to compute those parts, rather than repeating the work of computing the sum, or looking for min and max. 10. Create a function called arrClipFirstName that takes an integer value as an argument and changes any value in the array that is higher than the specified clip value to be the same as the clip value. This function could also be called "haircut", in that it takes values that are too high, and cuts them down to the allowable height. (Think of a scissor going through your hair and trimming the ones that are too long.) If the array is {2,4,6,7,3}, after arrClipFirstName (5) it should be {2,4,5,5,3}. a. When calling the arrClipFirstName 0 function from 11. Create a function called arrfindCountFirstName that takes an integer value as an argument and returns the count of the integer value in the array. If the array is {2,4,4,4,3}, arrfindCountFirstName (4) should return the count as 3 as there are three 45 in the array. When you are finished in this case submit the whole zipped package with the whole project instead of the files. Make sure that you use the default package. Please do not use java.util.Array for any of the functions Here is the main given below. Create an AILNTest Class when LN is your last name and include the following two methods in there. Please do not change the main or the method names included in the testDataBuffer method except for putting your firstname in. public static void main(String[] args) \{ int [] arr 0={2,1} int [] arr 1={1,2,3,4,5,6,7,8,9,10}; int [] arr 2={2,4,6,8,10,12,14,16,7, 6,22,8,9,16,5,2,7,8,12,2,0,14,17,19,22 3; arrintFirstName Al= new arrIntFirstName ( arr0); arrintFirstName A2= new arrintFirstName ( arrl ); arrIntFirstName A3= new arrintFirstName ( arr2); testDataBuffer( A1); testDataBuffer ( A2); testDataBuffer( A3); \} public static void testDataBuffer( arrIntFirstName A ) \{ A.arrDisplayFirstname(); System.out.println("Sum of Array: " + A. arrTotFirstname () ); System.out.println("Max of Array: " + A. arrMaxFirstname () )
