You have to design your own Java console application about any valid problem that your application must solve. Your solution can include solving a business problem, a new idea or even a game. Your application must make use of concepts such as arrays, loops, inheritance, constructors and information hiding. Output must be shown in the form of a report using the console.  

In your solution, make use of as many concepts, and components dealt with in this course, but pay special attention to the following learning units: • Learning Unit 1: Advanced arrays. • Learning Unit 2: Introduction to inheritance.

The statements below shows the declaration of an array:

String[] Municipality ={”Steve Tshwete”, “Nkomazi”, “City of Mbombela”, “Govan Mbeki”};

1) Make use of a loop of your choice and write statement(s) that will display all array elements indicating the Municipality’s name as follows:

Municipality 1: Steve Tshwete

Municipality 2: Nkomazi

Municipality 3: City of Mbombela

Municipality 4: Govan Mbeki

1) Write a statement that will replace array element Nkomazi with White River.

3) What is the array length?

4) Make use of a loop of your choice and write statement(s) that will display all Municipalities, considering effects of question (2), starting with the last Municipality as shown below:

Municipality 4: Govan Mbeki

Municipality 3: City of Mbombela

Municipality 2: Nkomazi

Municipality 1: Steve Tshwete

Define Exception Handling. Write a java program to create a user defined

exception for the following

a) Create a student class and get the name of the student and 3 subject marks

b) Find the length of the name. If the length > 7 throw LengthException

c) Find the average of marks, if avg < 50 throw FailedException

d) If avg < 75 && avg > 50 throw NotFirstClassException

e) If avg > 75 throw FirstClassException

Create a program that when run with two numbers as CMD arguments, it prints out the difference

and product separated by space[Hint: CMD arguments need to be converted to integers]:

Sample run 1: 

java lab02_task02 12 3 

Output: 9 36 

Sample run 2: 

java lab02_task02 2 5

Output: -3 10

12.8 (LAB) Fun With Branching - FINAL

For this project you will write a Java program that will run a simple math quiz. Your program will generate two random integers between 1 and 20 and then ask a series of math questions. Each question will be evaluated as to whether it is the right or wrong answer. In the end a final score should be reported for the user. (See below for how to generate random numbers).

Sample Ouptut This is a sample transcript of what your program should do. Values in the transcript in BOLD show the user inputs. So in this transcript the user inputs 33, Jeremy, 24, -16, and 80 the rest is output from the program.

Create a window (program) that will run as a standalone application. Your program must contain the following components:

 A label

 A button

 A check box

 A text field with a vertical scroll bar
