AP CSA Arrays (6.1)

Which of the following code segments, when appearing in another method in the same class as getValue, will print the value 70?

• int arr = {40, 30, 20, 10, 0};

  System.out.println(getValue(arr, 1, 2));

• int[] arr = {40, 30, 20, 10, 0};

  System.out.println(getValue(arr, 1, 2));

• int[] arr = {50, 40, 30, 20, 10};

  System.out.println(getValue(arr, 1, 2));

• int arr = {40, 30, 20, 10, 0};

  System.out.println(getValue(arr, 2, 1));

• int arr = {50, 40, 30, 20, 10};

  System.out.println(getValue(arr, 2, 1));

Which of the following code segments, appearing in the same class as the addNum method, will result in array2 having the contents {0, 0, 13, 0, 9, 0, 0}?

• int[] array1 = {5, 2, 8, 6, 4, 3, 9};

  int[] array2 = addNum(array1, 2, 4, 5);

• int[] array1 = {-5, -5, 13, 0, 9, 0, 0};

  int[] array2 = addNum(array1, 2, 4, 5);

• int[] array1 = {5, 2, 8, 6, 4, 3, 9};

  int[] array2 = addNum(array1, 3, 5, 5);

• int[] array1 = {5, 8, 2, 4, 6, 3, 9};

  int[] array2 = addNum(array1, 2, 4, 5);

• int[] array1 = {0, -5, 8, 0, 9, 0, 0};

  int[] array2 = addNum(array1, 2, 4, 5);

Consider the following code segment.

int[] arr = {1, 2, 3, 4, 5};

Which of the following code segments would correctly set the first two elements of array arr to 10 so that the new value of array arr will be {10, 10, 3, 4, 5}?

• arr[0] = 10;

  arr[1] = 10;

• arr[1] = 10;

  arr[2] = 10;

• arr[0, 1] = 10;

• arr[1, 2] = 10;

• arr = 10, 10, 3, 4, 5;

• I only

• II only

• III only

• I and II

• I and III

Consider the following method, which is intended to return the number of strings of length greater than or equal to 3 in an array of String objects.

• II only

• III only

• I and III only

• II and III only

• I, II, and III
