Chapter 8.2, Problem 16STQ
Consider the code below, which was discussed in the previous section:
Student joe = new Student(“Joe Student”, 2001);
System.out.printin(joe.tostring());
Why is the output on two lines instead of being all on one line?

Instructor note:
This lab is part of the assignment for this chapter.
This lab uses two Java files, LabProgram.java and SimpleCar.java. The SimpleCar class has been developed and provided to you already. You don't need to change anything in that class. Your job is to use the SimpleCar class to complete the specified tasks in the main() method of LabProgram.java
Given two integers that represent the miles to drive forward and the miles to drive in reverse as user inputs, create a SimpleCar object that performs the following operations:
Drives input number of miles forward
Drives input number of miles in reverse
Honks the horn
Reports car status
The SimpleCar class is found in the file SimpleCar.java.
Ex: If the input is:
100 4
the output is:
beep beep Car has driven: 96 miles
We're going to explore the law of large numbers here with a dice rolling program. Seed the random number generator with the current time and then roll three 6-sided dice (often described as 3d6) a total of 1,000,000 times and keep track of the number of times each sum 3 - 18 occurs.
Be sure to separate all functions and methods (if you chose to use a class or structure) into both the prototype and an implementation below the main.
1. Build a regular c-type function that returns a random number between 3 - 18. This will simulate a single roll of three dice. Use the prototype:
int rollDice(void);2. In the main, roll the dice 1,000,000 times and tally up the results in an array. I DO NOT want each individual roll printed to screen. Let the index represent the number rolled and the value will represent the number of times that number has been rolled. For example,
a[3] = 5357 a[4] = 14750...a[18] = 4981
This array set-up will mean that the result 3 occurred 5,357 times and the…
First, you need to design, code in Java, test and document a base class, Student. The Student class will have the following information:
A. Title of the student (eg Mr, Miss, Ms, Mrs etc)B. A first name (given name)C. A last name (family name/surname)D. Student number (ID) – an integer number (of type long)E. A date of birth (in day/month/year format – three ints) - (Do NOT use the Date class from JAVA)The student class will have at least the following constructors and methods:(i) two constructors - one without any parameters (the default constructor), and one with parameters to give initial values to all the instance variables.(ii) a reasonable number of set and get methods.(iii) methods to compute the final overall mark and the final grade (which will be overridden in the respective child classes). These two methods will be void methods that set the appropriate instance variables. Remember one method can call another method. If you prefer, you can define a single method that sets…
