What will be the value of x after the following code is executed? int x = 10; while (x < 100) { x += 10; }

A loop that repeats a specific number of times is known as a(n) ________ loop

This type of loop will always be executed at least once.

What will be the values of x and y as a result of the following code? int x = 25, y = 8; x += y++;

A ________ is a value that signals when the end of a list of values has been reached.

Assume that inputFile references a Scanner object that was used to open a file. Which of the following while loops shows the correct way to read data from the file until the end of the file is reached?

A for loop normally performs which of these steps?

How many times will the following do-while loop be executed? int x = 11; do { x += 20; } while (x > 100);

Before entering a loop to compute a running total, the program should first

The ________ is ideal in situations where the exact number of iterations is known

What will be the value of x after the following code is executed? int x = 10; for (int y = 5; y < 20; y +=5) x += y;

How many times will the following do-while loop be executed? int x = 11;

How many times will the following for loop be executed? for (int count = 10; count <= 21; count++) System.out.println("Java is great!");

What will be the value of x after the following code is executed? int x, y = 15; x = y--;

What does the following code do? Scanner keyboard = new Scanner(System.in); String filename; System.out.print("Enter the filename: "); filename = keyboard.readString(); PrintWriter outFile = new PrintWriter(filename);

The ________ loop is ideal in situations where you always want the loop to iterate at least once.

Given the following statement, which statement will write the string "Calvin" to the file DiskFile.txt?

In all but rare cases, loops must contain within themselves

Which of the following statements opens a file named MyFile.txt and allows you to read data from it?

Assuming that inputFile references a Scanner object that was used to open a file, which of the following statements will read an intfrom the file?

If a loop does not contain within itself a way to terminate, it is called

A loop that executes as long as a particular condition exists is called a(n) ________ loop

A(n) ________ is a special value that cannot be mistaken as a member of a list of data items and signals that there are no more data items from the list to be processed.

The variable used to keep the running total is called a(n)

In general, there are two types of files:

What will be the value of x after the following code is executed? int x = 10; for (int y = 5; y < 20; y +=5) x += y;
