Machine Problem #7. Using the concept ArrayList, write a method-oriented Java program that will take 10 integer inputs from user and print the following: number of positive numbers, number of negative numbers, number of odd numbers, number of even numbers, number of 0s. Note: 0 is not considered a positive number. ClassName: MethodArrayListArraySearch Sample Input/Output Enter values of the Array List -9 -8 10 0 5 6 0 8 -12 14 Number of positive numbers: 7 Number of negative numbers: 3 Number of odd numbers:2 Number of even numbers: 6 Number of 0s: 2 Machine Problem #8. Write a method-oriented Java program that considers an integer ArrayList, the number of elements in which is determined by the user. The elements are also taken as input from the user. Get the sum of all odd numbers and sum of all inputted values. Class Name: MethodArrayListSumofNumbers Sample Input/Output Enter the length of the ArrayList: 5 The value of an ArrayList at index 0: 15 The value of an ArrayList at index 1: 14 The value of an ArrayList at index 2: 13 The value of an ArrayList at index 3: 12 The value of an ArrayList at index 4: 50 The sum of odd numbers is: 27 The sum of all inputted numbers is: 116
Machine Problem #7. Using the concept ArrayList, write a method-oriented Java program that will take 10

Machine Problem #8. Write a method-oriented Java program that considers an integer
ArrayList, the number of elements in which is determined by the user. The elements are also
taken as input from the user. Get the sum of all odd numbers and sum of all inputted values.
Class Name: MethodArrayListSumofNumbers
Sample Input/Output
Enter the length of the ArrayList: 5
The value of an ArrayList at index 0: 15
The value of an ArrayList at index 1: 14
The value of an ArrayList at index 2: 13
The value of an ArrayList at index 3: 12
The value of an ArrayList at index 4: 50
The sum of odd numbers is: 27
The sum of all inputted numbers is: 116

Machine Problem #9. Write a method-oriented Java program using the concept of string
ArrayList, the number of elements in which is determined by the user. The elements are also
taken as input from the user. Ask the user to input names and determine how many times each
name repeats ignoring the case (it means uppercase and lowercase are the same)
Class Name: MethodArrayListStringSearch
Sample Input/Output
Enter the number the size of the ArrayList: 5
You need to input a total of 5 names, Input them now.
