a. Write a complete Java program that prints digits of a given number separately. [2 mark] For example, if the given input 329, the output would be: 3 2 9 b. You must Show the details of Tracing the code above that you followed to get the answer [1 marks] 2. Wrapper Class: Write a complete Java program as follows: a. Create two boolean variables (a and b) and give them values. [1 mark] b. Compare the two variables created above using compare() method that takes two boolean values in the parameter which are to be compared. [1 mark] c. What are possible outputs emerged from the compare() method above? Explain all the cases [1 mark] 3. Write a Java program the design the following calss: Build a class GymMember that has the following: a. Attributes: name (String), ID(int), JoiningDate (Date class). Use this for date type: Date JoiningDate = new Date(int year, int month, int date) [4 marks] b. Build a constructor that accepts three parameter name, ID, and Joining date. Then initialize the objects' attributes. c. Build a default constructor with empty body and no parameters d. In the main method, create two GymMember objects gland g2 using value constructor with arguments (parameters), and print their ids. e. Also, in the main method, create a third Gym Member object g3 using the default constructor f. Call a method Check JoiningDate() on this object g3. g. Print the result of CheckJoiningDate() method. h. In the GymMember class, build a method named CheckJoiningDate() that has no parameters. The method checks the joining date of this object g3, and if the joining year 2019 or before; prints the following: "Congratulations, you've earned a free membership next month"
