Question 1 ( Java Programming) 1. Create a class called Parents with private variables of type String, mother and father, and also two private variables for their birthday year in type integer. (a) Create a constructor to initialize all four variables. (b) Create another constructor (overloading) to initialize variables mother and father only. (c) Create getters and setters for the variables. (d) Create a method called parentsAge which display your parents’ age based on the birthday year that you input in the test class. 2. Create a child class for Parents called Siblings (a) Create two variables called brother and sister of type String. (b) Create a constructor to initialize all variables including the variables from Parents class. All together there should be six number of arguments. (c) Create another constructor (overloading) that initialize all the variables including variables from Parents (minus the age). All together there should be four number of arguments. (d) Create a method called myFamily to display mother, father, brother and sister’s name. (e) Create a method called mySelf which calls method favoriteHobby from a class called Hello. The relationship between class Siblings and class Hello is has-a relationship (composition). 3. Create a class called Hello. (a) Create a method called favoriteHobby which displays “My hobby is playing games”. 4. Create a class called testClass to execute all the classes above. (a) Create Scanner object to input father and mother’s birthday years. (b) Create object to call class Parents (with two arguments)to call setter methods to set the parents’ age. Assign birthday years as their parameters. (c) Call method parentsAge (d) Create object to call class Siblings (with four arguments) (e) Call method myFamily (f) Call method myself
