Consider the following code segment. int x = 0; x++; x += 1; x = x + 1; x -= -1; System.out.println(x); What is printed when the code segment has been executed?

Consider the following method. public int getTheResult(int n) { int product = 1; for (int number = 1; number < n; number++) { if (number % 2 == 0) product *= number; } return product; }   What value is returned as a result of the call getTheResult(8) ?

A store sells rope only in whole-foot increments. Given three lengths of rope, in feet, the following code segment is intended to display the minimum length of rope, in feet, that must be purchased so that the rope is long enough to be cut into the three lengths. For example, for lengths of 2.8 feet, 3 feet, and 5 feet, the minimum length of rope that must be purchased is 11 feet. For these inputs, the code segment should display 11. As another example, for lengths of 1.1 feet, 3.2 feet, and 2 feet, the minimum length of rope that must be purchased is 7 feet. For these inputs, the code segment should display 7. double len1; double len2; double len3; double total = len1 + len2 + len3; int minLength = (int) (total + 0.5); System.out.print(minLength); Which of the following best describes the behavior of the code segment?

Consider the following class definition. public class ExamScore { private String studentId; private double score;   public ExamScore(String sid, double s) { studentId = sid; score = s; }   public double getScore() { return score; }   public void bonus(int b) { score += score * b/100.0; } } Assume that the following code segment appears in a class other than ExamScore. ExamScore es = new ExamScore(“12345”, 80.0); es.bonus(5); System.out.println(es.getScore()); What is printed as a result of executing the code segment?

Consider the following code segment. int j = 10; int k = 8; j += 2; k += j; System.out.print(j); System.out.print(” “); System.out.println(k); What is printed when the code segment is executed?

Consider the following class declaration. public class Sample { private int a; private double b;   public Sample(int x, double y) { a = x; b = y; }   // No other constructors } The following method appears in a class other than Sample. public static void test() { Sample object = new /* missing constructor call */ ; } Which of the following could be used to replace /* missing constructor call */ so that the method will compile without error?

Consider the following code segment. double d = 0.25; int i = 3; double diff = d – i; System.out.print((int)diff – 0.5); What is printed as a result of executing the code segment?

A student has created a Car class. The class contains variables to represent the following. A String variable called color to represent the color of the car An int variable called year to represent the year the car was made A String variable called make to represent the manufacturer of the car A String variable called model to represent the model of the car The object vehicle will be declared as type Car. Which of the following descriptions is accurate?

Consider the following code segment, which is intended to calculate the average of two quiz scores. double avg = 15 + 20; avg /= 2; Which of the following best describes the behavior of the code segment?

Consider the following code segment, which is intended to display 0.5. int num1 = 5; int num2 = 10; double ans = num1 / num2; System.out.print(ans); Which of the following best describes the error, if any, in the code segment?
