Programming Techniques
Practical Pre-work
Complete the following exercises from the Gaddis textbook prior to your Week 8 practical class. You may check your answers against the answers published in vUWS. Discuss your solutions in the practical class with your tutor in week 8 if there are any that you don't understand.

Week 8 Practical Exercises
During the Week 8 practical complete the following exercises using the Eclipse IDE to produce working Java code.
Coding Standards: When writing code in this unit you are required to adhere to the Coding Standards and General Principles as defined in the FAQ in vUWS. Your code for the following exercises should adopt these standards and general principles.
1. Write a Java program that will obtain 10 positive integers from the user via the keyboard; as the values are entered by the user store the values in an array. After the values have all been entered and stored in the array, process the array to determine the largest value, smallest value, and the average of the 10 values stored in the array. Your solution must incorporate appropriate methods.
2. Create a copy of your solution to question 1. Edit the copy of the program so that the input numbers are obtained from a text file named numbers.txt instead of from the keyboard. Use a text editor to create the numbers.txt file yourself. Place in the file any number of numbers and test your program. Test the program with different sized files with different sets of numbers. Make sure your code works correctly if the file isn't found, if it exists but doesn't have any data in it, or, if the file has too many values to fit into the array. Your solution must incorporate appropriate methods.
Optional MyProgrammingLab Exercises
These exercises are completely optional. To complete the following exercises you will need to have registered for the Programming Techniques course in MyProgrammingLab. Instructions to register for MyProgrammingLab are published in the "MyProgrammingLab Registration" document that can be found in the "Getting Started" link in vUWS.
To register you will need a MyProgrammingLab access code (comes with the Value Pack version of the text book or can be purchased separately online as part of the registration process) and you should use the ‘Course ID' or ‘Section Access Code' UOFW-29746-XYMH-34
A. Requirements
For each question listed in section B you must
a) use the name for the class file(s) as identified in the question
b) include your authorship details at the top of the file in code comments (see item 3.1 in Section C of this document for details)
c) adhere to the coding standard as identified in the Google Java Style Guide (see Section C of this document for details)
d) reference all sources that you used for inspiration of your solution as per
Section D of this document
e) Ensure that your java code compiles and runs in Eclipse 4.5.3 (Neon.3)
B. Questions
Complete the following questions using the Eclipse IDE to produce working Java code files.
1) Question: Exercise 1 from Week 7 Practical Exercises (Car Class including the additional requirements)
