A java class named LastnameFirstnameA2 which asks the user to define the length of an array (not more than 10) and then accept the integer elements based on the length defined (No Command Line Parameters) for two arrays and follow the instructions: 2. If the length of the array is invalid or the inputs are not integers, you should print a "Usage" statement exactly as shown below. 3. If the arrays are longer than the set length, the first elements should be taken. a. For example, length = 3, input array = [1 2 3 4 5] the input should be taken as [1 2 3] 4. When inputs are correct, your file must contain the following: a. A method that returns the user's array. b. A method that prints the array passed to it. c. A method returns the sorted array of the FIRST array. Do not change the original array. Any sorting algorithm is fine but do not use APIs! Hint: You can store a copy by writing a "copy" function. d. Print this array. e. A method returns the reversed array of the SECOND array. Do not change the original array. Hint: You can store a copy by using the above written "copy" function. f. Print this array. g. A method that prints the count of even and odd numbers. h. Print the counts of even and odd numbers for both the arrays using above method. i. A method to return the sum of the elements of the array. j. Print the sum of the two arrays. Note: The print statement is different if the sum is equal and different if they are different. (Check example outputs below carefully.) 5. Pay careful attention to the above requirements. "Print" and "return" are two different things. 6. You can write additional methods or classes if needed. 7. You can use java.util.Scanner to read user input (Refer documentation https://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html for more details) 8. Your output should be like the following samples. Make sure these matches EXACTLY. Also test for additional test cases to ensure the program works correctly.
