Document Summary

2. 1 the place of definitions in critical thinking. To claim something is true is to assert it. Lets call what we assert using a complete sentence a proposition. Three propositions: bill s wife is mad, bill s wife is mad at him, bill has a wife. We can assert something that is false and claim that it is true. When a sentence has two proposition joined by and . Peter is tall and bob is short. Both true for the entire statement to be true. If one of them is false then the entire conjunction is false too. Its only true when both conjuncts are true. Either john is late or my clock is fast: one is not asserting that john is late and one is not asserting that the clock is fast. If it rains, then the picnic will be cancelled. A statement of the form if p, then q. Does not assert the antecedent or the consequent.

12. Which of the following is NOT specified for the formal parameters in a function (or method) definition? A. type B. name C.value D. position in the parameter list The next set of four problems is an extended "matching" problem. Each problem shows a Processing sketch. Enter the letter that corresponds to the output. The possible choices are not all used and some may be used more than once.

Programming Writing Montreal Maps In the following questions, you will write classes that allow one to suggest a route to get from one point to another on a metro or train line. Note that for all of these questions, we will make the simplifying assumption that the earth is flat and that everything resides in 2 dimensions. (There were metros before Columbus and Galileo, right?) 6. Write a class MetroStation in which you define a new type MetroStation. (10 points) A MetroStation is defined to have the following private properties: • String name This represents the name of the metro station (e.g. Atwater, McGill, etc) • double xPosition This represents the x location of the metro station. • double y Position This represents the y location of the metro station. An MetroStation object should have the following public methods/behaviors defined on it. • A constructor that takes as input a String stationName, a double x, and a double y. The constructor should initialize the properties name, xPosition, and yPosition to these three values respectively • A method getName() which returns the name of the Metrostation. • A method get XPosition () which returns the x location of the Metrostation • A method get Position () which returns the y location of the Metrostation • A method equals (Metrostation other) which returns a boolean representing whether the name property of the this MetroStation is equal to the name property of other.

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
