Control Structures (H6)

Question 1

used to control the execution flow of the program.

Answer 1

Control Statements

Question 2

Java Types of Control Statements

Answer 2

1. Selection
2. Repetition
3. Branching

Question 3

Selection statements are decision-making statements that include if, if-else, and switch statements.

Answer 3

Selection

Question 4

The _ decision construct is followed by a logical expression wherein data is compared, and a decision is
made depending on the comparison result.

Answer 4

if statement

Question 5

It is an extension of the if statement that provides an alternative action when the if statement results in a
false outcome.

Answer 5

if-else statement

Question 6

the set of statements between two curly braces ({, }).

Answer 6

block

Question 7

It is considered an easier implementation of the if-else statement. It is used whenever there are multiple values possible for a variable. This statement successfully lists the value of a variable or an expression against a list of byte, short, char, or int primitive data types only. The statements linked with that case constant are executed when a match is found.

Answer 7

switch statement

Question 8

The ______ must always be the last option in the switch construct if used

Answer 8

default label

Question 9

are looping statements that include while, do-while, and for statements.

Answer 9

Repetition statements

Question 10

It is a looping construct that continues until the evaluating condition becomes false. The evaluating condition must be a logical expression and must return a true or a false value. The variable checked in the Boolean expression is called the loop control variable.

Answer 10

while loop statement

Question 11

It is a looping construct that continues until the evaluating condition becomes false. The evaluating condition must be a logical expression and must return a true or a false value. The variable checked in the Boolean expression is called the _____.

Answer 11

loop control variable

Question 12

Another looping statement that lists the conditions after the statements to be executed. This statement can be considered a post-test loop statement. First, the do block statement is executed, and then, the condition given in the while statement is checked.

Answer 12

do-while loop statement

Question 13

The while and do-while loops are used whenever the number of repetitions or iterations is _____. Iterations refer to the number of times the loop body is executed.

Answer 13

unknown

Question 14

Compared to while and do-while statements, the _____ is used when iterations are known in advance. This looping statement can be used when determining the square of each of the first ten numbers.

Answer 14

for loop statement

Question 15

gives the loop variable an initial value. This expression is executed only once when the control is passed to the loop for the first time.

Answer 15

Initialization

Question 16

executes the condition each time. The control passes to the start of the loop. The loop’s body is executed only after the condition has been checked. If the condition is true, the loop is executed. Otherwise, the control is passed to the following statement.

Answer 16

Test

Question 17

this expression is always executed when the control returns to the beginning of the loop.

Answer 17

Increment/Decrement

Question 18

These statements transfer control to another part of the program.

Answer 18

Branching

Question 19

It is a branching statement that can be labeled or unlabeled. This statement is used for breaking loop
executions such as of while, do-while, and for. It also terminates the switch statements.

Answer 19

break statement

Question 20

which breaks the innermost loop or switch statement.

Answer 20

break

Question 21

which breaks the outermost loop in the series of nested loops. A nested loop is a loop that exists within another loop.

Answer 21

break label;

Question 22

It is used in looping statements such as while, do-while, and for to skip the current iteration of the loop
and resume to the next iteration.

Answer 22

continue statement

Question 23

It transfers the control to the caller of the method. It is used to return a value to the caller method and
terminates the execution of the method. It has two forms: one that returns a value and the other that
cannot return a value. The returned value type must match the return types of the caller method.

Answer 23

return statement

Question 24

return statement syntax

Answer 24

• return values;
• return; – returns nothing, so this can be used when a method is declared with a void return type.
• return expression; – returns the value evaluated from the expression.
