System.out.println(w + " " + x);

• 40 20

A student is developing a program that will store information about players of a video game, including each player’s score and amount of time remaining, in seconds. Which of the following is the most appropriate design?

• An Information class with Player instance variables for the score and the amount of time remaining

• A Player class with int instance variables for the score and the amount of time remaining

• A Player class, a Score class, and a RemainingTime class, each with an int instance variable

• A Score class and a RemainingTime class, each with a Player instance variable

Which of the following expressions evaluates to 3.5?

• (double) 2 / 4 + 3

• (double) 2 / (4 + 3)

• (double) (2 / 4) + 3

• (double) (2 / 4 + 3)

String oldStr = "ABCDEF";

String newStr = /* missing code */;

System.out.println(newStr);

Which of the following expressions can be used to replace /* missing code */ so that the code segment prints the string "BCEF"?

• oldStr.substring(1, 2) + oldStr.substring(4)

• oldStr.substring(1, 2) + oldStr.substring(5)

• oldStr.substring(1, 3) + oldStr.substring(4)

• oldStr.substring(1, 3) + oldStr.substring(5)

Consider the following partial class definition.

Assume that SomeClass object obj has been properly declared and instantiated in a class other than SomeClass.

Which of the following statements will compile without error?

• int x = obj.getA();

• int x = obj.myA;

• int x = SomeClass.getA();

• int x = getA(obj);

Which of the following methods can be added to SomeClass to allow other classes to modify the value of myA?

• public void setA(int newA)

  { myA = newA;

  }

• private void setA(int newA)

  { myA = newA;

  }

• public void setA(int newA)

  { newA = myA;

  }

• private void setA(int newA)

  { newA = myA;

  }

The following categories are used by some researchers to categorize regions as urban, suburban, or rural based on

population density.

• An urban region is a region with more than 3,000 people per square mile.

• A suburban region is a region with between 1,000 and 3,000 people, inclusive, per square mile.

• A rural region is a region with fewer than 1,000 people per square mile.

Consider the following method, which is intended to categorize a region as urban, suburban, or rural based on the

population density of the region.

public static String getCategory(int density)

{

/* missing code */

}

Which of the following code segments can replace /* missing code */ so the getCategory method works as

intended?

• String category;

  if (density > 3000)

  { category = "urban";

  }else if (density >= 1000)

  { category = "suburban";

  } else {

  category = "rural";

  }

  return category;

• String category;

  if (density > 3000)

  { category = "urban";

  } else if (density <= 3000)

  { category = "suburban";

  } else {

  category = "rural";

  }

  return category;

• String category = "rural";

  if (density > 3000)

  { category = "urban";

  }

  if (density >= 1000)

  { category = "suburban";

  }

  return category;

• String category = "urban";

  if (density < 1000)

  { category = "rural";

  }

  if (density >= 1000)

  { category = "suburban";

  }

  return category;

Consider the following class definition.

Which of the following statements will cause a compilation error?

• Student a = new Student();

• Student b = new Student("Juan");

• Student c = new Student("Juan", 15);

• Student d = new Student("Juan", "15");

Consider the following method, which is intended to return true if the distance between d1 and d2 is no more than

tolerance units, and to return false otherwise.

For example, almostEqual(7.9, 7.8, 0.15) should return true because the distance between 7.9 and 7.8 is less than

0.15, and almostEqual(54.124, 54.126, 0.001) should return false because the distance between 54.124 and 54.126 is

greater than 0.001.

Which of the following can be used to replace /* missing code */ so that the method will work as intended?

• return (d1 - d2) <= tolerance

• return ((d1 + d2) / 2) <= tolerance

• return Math.abs(d1 - d2) <= tolerance

• return Math.abs((d1 + d2) / 2) <= tolerance

Consider the following code segment.

int a = 3 + 2 * 3;

int b = 4 + 3 / 2;

int c = 7 % 4 + 3;

double x = a + b + c;

What is the value of x after the code segment is executed?

• 14.0

• 18.0

• 20.0

• 20.5
