Assignment Tasks Note: Students can start to work now on partial tasks. Other tasks need the knowledge in 2/22 lecture. After we cover 2/22 lecture, you can complete the leftover tasks in the entire assignment. Part1: 1.1 Problem Descriptions Complete the missing code of a Java program which receives the user inputs of name and the year of birth and reports the person's age and classification (minor, adult, or senior). The following code you need to complete is described as following (the missing code items are denoted by TODO comment: public class AgeClassifier { private String name; //the name private int birthYear; //the year /* the constructor method */ public AgeClassifier (String sName, int year ) { name = sName; birthYear = year; } /* this method return the age */ public int getAge() { //TODO: add missing code to calculate and return the age of the person /* this method return the age */ public int getAge() { //TODO: add missing code to calculate and return the age of the person } /* this method return the age classification*/ public String getAgeClassification(int age) { //TODO: add missing code to classify //the input age into three types: minor, adult, and senior } public static void main(String args []) { Scanner user_inputs = new Scanner(System.in); System.out.print("Enter the name: "); String name = user_inputs.nextLine(); System.out.print("Enter the year of birth: "); int year = user_inputs.nextInt(); 1/TODO: add missing code below to print the name, age //and the age classification of that person } } Check the following section for the detailed specifications of your program. 1.2 Class Design Specification } Check the following section for the detailed specifications of your program. 1.2 Class Design Specification 1. The name of the class is called Age Classifier (also means the file name is Age Classifier.java) 2. The class has one integer variable birthYear to store the year of birth and one String variable name to store the name of the person 3. The class has four methods: a. AgeClassifier(String sName, int year): This constructor method has two input arguments to initialize the values of name and birthYear. This method is already completed. b.getAge(): This method calculate and return the age of the person. C. getAgeClassification(int age): This method receives an input (age) and return a String that denotes the age classification. There are three categories: "Minor" if the age is less than or equals to 19 "Adult" if the age is between 20 and 65 - "Senior" if the age is greater than 65 d. main(): This method will create at least one instance of the Age Classifier class with two inputs from the user by using Scanner class. Then you should use System.out.println to print the name, age, and the age classification of the user. Below is the sample outputs of the program . Enter the name: Test Person Enter the year of birth: 1996 Name. Test Person een 20 arid 65 Il the age is - "Senior" if the age is greater than 65 d. main(): This method will create at least one instance of the Age Classifier class with two inputs from the user by using Scanner class.
