You have decided to start lifting weights at the gym. You would like to track your progress on each exercise. To make it easier to enter data, you are designing an application based on the day of exercise that enables you to enter additional information such as your weight, time, health (excellent, good, tired, weak, sick), and general comments. For most weight-lifting exercises, you perform multiple lifts (repetitions) within a set, then change the weight for a new set and do another set of repetitions. Design a normalized database for tracking your exercises. Date: Weight: Comments Total time: Exercise Weight/set # Reps Comments
Please show your work as well as primary and foreign keys.

File account.java (see previous exercise) contains a definition for a simple bank account class with methods to withdraw, deposit, get the balance and account number, and return a string representation. note that the constructor for this class creates a random account number. save this class to your directory and study it to see how it works. then write the following additional code: 1. suppose the bank wants to keep track of how many accounts exist. a. declare a private static integer variable numaccounts to hold this value. like all instance and static variables, it will be initialized (to 0, since it’s an int) automatically. b. add code to the constructor to increment this variable every time an account is created. c. add a static method getnumaccounts that returns the total number of accounts. think about why this method should be static - its information is not related to any particular account. d. file testaccounts1.java contains a simple program that creates the specified number of bank accounts then uses the getnumaccounts method to find how many accounts were created. save it to your directory, then use it to test your modified account class.
