Question

Lab 1: InheritanceTest Write a program called InheritanceTest1.java to support an inheritance hierarchy for class Point–Square–Cube. Use Point as the superclass of the hierarchy. Specify the instance variables and methods for each class. The private data of Point should be the x-y coordinates, the private data of Square should be the sideLength, and the private data of Cube should be depth. Provide applicable accessor methods, mutator methods, toString() methods, area() method, and volume() method to all classes. Write a program that instantiates objects of your classes, tests all instance methods, and outputs each object’s area and volume when appropriate. Lab 2: InheritanceTest2 Implement an inheritance hierarchy for Account class, Checking Account class, and Savings Account class. CheckingAccount class has a special field called withdrawFee and SavingAccount has a special field called interestRate. Write a program that instantiates objects of all your classes, tests all instance methods, and display the balance of each account. Lab 3: FitnessHealthInformation GymsRUs has a need to provide fitness/health information to their clients, including BMI and maximum heart rate. Your task is to write a console program to do this. Body mass index (BMI) is a measure of body fat based on a person’s height and weight. BMI can be used to indicate if you are overweight, obese, underweight, or normal. The formula to calculate BMI is The following BMI categories are based on this calculation. Category BMI Range Underweight less than 18.5 Normal between 18.5 and 24.9 Overweight between 25 and 29.9 Obese 30 or more Max heart rate is calculated as 200 minus a person’s age. FUNCTIONAL REQUIREMENTS Design and code a class called HealthProfile to store information about clients and their fitness data. The attributes (name, age, weight, and height) are private instance variables. The class must include the following methods. method description setName Receives a value to assign to private instance variable setAge Receives a value to assign to private instance variable setWeight Receives a value to assign to private instance variable setHeight Receives TWO inputs (height in feet, inches). Converts and stores the total INCHES in private instance variable getName Returns private instance variable getAge Returns private instance variable getWeight Returns private instance variable getHeight Returns private instance variable (inches) getBMI Calculates and returns BMI getCategory Returns category based on BMI getMaxHR Calculates and returns maximum heart rate Create a SEPARATE TEST CLASS, Lab1Main, to prompt for user input and display output using the HealthProfile class. Process multiple inputs using a loop. You can assume all user input is valid. SAMPLE OUTPUT Enter name or X to quit: John Smith Your age: 31 Your weight: 185 Your height - feet: 5 Your height - inches: 10 Health Profile for Marc Legagneur BMI: 19.3 BMI Category: Fit Max heart rate: 185 Enter name or X to quit: John Smith Your age: 31 Your weight: 120 Your height - feet: 5 Your height - inches: 2 Health Profile for Magic Jones BMI: 21.9 BMI Category: normal Max heart rate: 170 Enter name or X to quit: X
