Each of the following code segments is intended to print the word Hello. Which of the following code
segments works as intended?
I. System.out.print("Hello");
II. System.out.print(Hello);
III. System.out.print(He);
System.out.print(llo); - A. I only
Which statement correctly declares a variable that can store a temperature rounded to the nearest tenth
of a degree? - B. double patientTemp;
A teacher determines student percentages in a course as the points a student earns divided by the total
points available in the grading period. Points are awarded only in whole number increments, but student
percentages are to be stored as decimals.
The following code segment appears in a program used to compute student percentages. Points that a
student earns are stored in pointsEarned, the total points available in the grading period are stored in
totalPoints, and the student percentage is stored in percentage.
int pointsEarned;
/* missing code */
Which of the following is most appropriate to replace /* missing code */ in the program? - C. int
totalPoints;
double percentage;
Consider the following code segment:
/* data type 1 */ x = 0.5;
, AP Computer Science A 2024 exam
/* data type 2 */ y = true;
Which of the following best describes the data types that should be used to replace/* data type 1 */ and
/* data type 2 */ so that the code segment compiles without error? - D. The variable x should be
declared as a double and the variable y should be declared as a boolean.
Consider the following code segment.
int x;
int y;
x = 3;
y = /* missing expression */;
x = 1 + 2 * y;
System.out.print(x);
System.out.println(y);
Which of the following can be used as a replacement for /* missing expression */ so that the code
segment prints 94 ? - D. x + 1
The volume of a cylinder is equal to the height times the area of the circular base. The area of the
circular base is equal to π (pi) times the square of the radius.
The code segment below is intended to compute and print the volume of a cylinder with radius r and
height h. Assume that the double variables r, h, and pi have been properly declared and initialized.
/* missing code */
System.out.print(volume);
Which of the following can be used to replace /* missing code */ so that the code segment works as
intended?
I. double baseArea = pi * r * r;double volume = baseArea * h;
