Exam 6: Flow of Control, Part 2: Looping

while loops can be nested.

Which Java class enables us to read data easily from a file?

Evaluate this code segment, explaining any errors: 12 int count = 1; 13 int total = 1; 14 final int SENTINEL = -1; 15 int score;

Putting a semicolon after the loop condition of a while loop will most likely result in a(n) __________ or endless loop.

Curly braces around the loop body are optional if the loop body consists of only one statement.

How many times will a loop with the for loop header for ( i = 0; i < 6; i++ ) execute?

The body of a while loop is executed until the loop condition becomes __________.

When you use a while loop to compute the average of several values, what do you have to worry about when dividing the sum of these values by the number of these values?

How many times will a loop with the for loop header for ( i = 0; i <= 6; i++ ) execute?

What is the output of this code sequence? for ( int i = 5; i >= 0; i-- ) System.out.print( i + " " ); System.out.println( );

The hasNext method in the Scanner class returns true if the input has another token, and false otherwise.

In the do/while loop, the loop condition is tested at the end of the loop, instead of at the beginning, as in the while loop.

How many times will a loop with the for loop header for ( i = 1; i <= 6; i++ ) execute?

The while loop condition is a boolean expression.

When you use a while loop to compute the average of several values, what variables do you need to keep track of (in addition to holding the value being processed)?

The while loop is used to process each input value, one at a time, until a signal tells us that there is no more input. This is called:

What is the argument list for the nextFloat( ) method in the Scanner class?

When reading data from a file using a while loop, the typical condition to exit the loop is when you:

How many times will a loop with the for loop header for ( i = 5; i <= 15; i++ ) execute?

The loop condition is a boolean expression.
