Suppose you wish to use an array to solve a new problem. What is the first step to take
in finding a solution? CORRECT ANSWERS decompose the problem into steps
What is the output of the following code snippet?
int[] values = { 10, 20, 30, 7};
int[] numbers = values;
numbers[2] = 24;
values[3] = numbers[0] + 6;
System.out.println (numbers[2] + " " + numbers[3] + " " + values[2] + " " + values[3]);
CORRECT ANSWERS 24 16 24 16
What is the output of the following statements?
ArrayList<String> names = new ArrayList<String>();
names.add("Bob");
names.add(0, "Ann");
names.remove(1);
names.add("Cal");
names.set(2, "Tony");
for (String s : names)
{
System.out.print(s + ", ");
} CORRECT ANSWERS array list bound error
Assume the method doSomething has been defined as follows:
public static void doSomething (int[] values)
{
for (int i = 1; i < values.length; i++)
{
values[i - 1] = values[i];
, }
}
What does the method do? CORRECT ANSWERS It moves each element of the array
values to a lower index position and overwrites the first element.
What is the output of the following code snippet?
int[] values = { 1, 2, 3, 4};
values[2] = 24;
values[values[0]] = 86;
for (int i = 0; i < values.length; i++)
{
System.out.print (values[i] + " ");
} CORRECT ANSWERS 1 86 24 4
Consider the code snippet below:
int searchedValue = 42;
int pos = 0;
boolean found = false;
while (pos < values.length && !found)
{
if (values[pos] == searchedValue)
{
found = true;
}
else
{
pos++;
}
}
When the loop finishes what does the value of the boolean variable found indicate?
CORRECT ANSWERS whether or not the value 42 was found in the array
Consider the following code snippet:
int[][] arr =
{
{ 1, 2, 3 },
{ 4, 5, 6 }
};
int val = arr[0][2] + arr[1][2];
System.out.println(val);
What is the output of the given code snippet on execution? CORRECT ANSWERS 9
Which statement is true about the code snippet below?
