Document Summary

In your answers, i will be looking for evidence that you have considered the core concepts presented in lectures and that you have read and understood the assigned readings for the class. You should aim to engage with relevant theory and analytical tools, provide evidence for your assertions and make judicious use of examples and cases. This is to allow you sufficient flexibility to construct an argument based on what you consider to be the critical issues, rather than just regurgitating facts or summarizing arguments from different sources. Section 1 will be worth 80% of the final grade, while section 2 will be worth 20% of the final grade. You will be required to answer two essays questions, from a choice of. Below are seven questions, which should guide your review of the readings and lectures on the relevant themes/issues. The final wording of the test questions may vary slightly from the present version.

2. In this section you will be shown several classes. Inside the code for each class will be a question. You should provide your answer to the question inside the chart. Many of the questions will ask you whether a variable has changed or not. In cases that the variable being asked about is a primitive type, you should provide your answer based on the data stored in the primitive type. In cases that the variable being asked about is a reference type, you should provide your answer based on the data stored at the Object linked to by the reference type. For example, in the first snippet, the question asks about the variable x defined in the main method. Since x is a primitive type, you should answer YES if you think the variable x has had its value changed after the method methodOne() returns. All your answers should go in the chart below: (9 points) Part Answer to question x changed (circle one)? YES NO y changed (circle one)? a changed (circle one)? b changed (circle one)? d1 a changed (circle one)? b changed (circle one)? YES e words changed (circle one)? YES NO Values in array of array referred to by y: What is printed to the screen? (a) public class ReferenceTesti public static void methodOne (int x){ x++; public static void main(String[args) { int x = 0; methodOne (x); //IS THE DATA STORED OR REFERRED TO BY X THE SAME? (ANSWER IN CHART)

17. Which of the following are examples of compile-time errors? Write the letters corresponding to the correct answers on your answer sheet. (a) Accessing an array at index -1 (b) Dividing an integer by 0 (c) Passing an int value as input to a method that expects a double input argument (d) Accessing a variable outside of its scope. (e) Omitting a semi-colon at the end of a statement. For the next two questions, consider the following block of code: for (int i=0; i<5; i+=2) { for(int j=0; j<=i; j++){ System.out.println("Bubblegum");

Type of Errors For each of the following answer whether they would cause an compiler error, runtime error, or a bug. In other cases the mentioned error may not cause a problem for the computer and is merely a question of style. In this case you should choose "Style" In other cases the question may not cause a problem at all in which case you should answer "No Error" For the purpose of this question, you can use the following definitions: • Compiler error : An error that occurs during the compilation phase of your development. In this case no class file is produced. • Runtime error: An error that occurs while you are running your program. Your program starts to execute but terminates before the main method has finished executing. • Logical error or bug : An error that results in the wrong results being seen • Style error: The error does not make a difference to the computer but is something that may be considered bad code. 7. Omitting a semi-colon at the end of a variable assignment. (A) Compiler Error (B) Bug (logical) Error (C) Style (D) Runtime Error (E) No Error
