Java Chapter 5

Front 1

Typically, ___ statements are used for counter-controlled repetition and ___ statements for sentinel-controlled repetition.

Back 1

for, while

Front 2

The do...while statement tests the loop-continuation condition _________ executing the loop’s body; therefore, the body always executes at least once.

Back 2

after

Front 3

The ___ statement selects among multiple actions based on the possible values of an integer variable or expression, or a String.

Back 3

switch

Front 4

The ___ statement, when executed in a repetition statement, skips the remaining statements in the loop body and proceeds with the next iteration of the loop.

Back 4

continue

Front 5

The ___ operator can be used to ensure that two conditions are both true before choosing a certain path of execution.

Back 5

&&

Front 6

If the loop-continuation condition in a for loop header is initially ___, the program does not execute the for statement’s body.

Back 6

false

Front 7

Methods that perform common tasks and do not require a calling object are called ___ methods. These methods can be called by a reference to the class itself.

Back 7

static

Front 8

What is the general format of the for loop statement header.

Back 8

for (initialization; loopContinuationCondition; increment)

Front 9

T/F The break statement is required in the last case of a switch selection statement. If false explain why.

Back 9

f The break statement is used to exit the switch statement. The break statement is not required for the last case in a switch statement.

Front 10

T/F The expression ((x>y) && (a<b)) is true if either or both of its operands are true. If false explain why.

Back 10

f Both of the relational expressions must be true for the entire expression to be true when using the && operator.

Front 11

T/F An expression containing the || operator is true if either or both of its operands are true. If false explain why.

Back 11

t

Front 12

T/F The comma (,) formatting flag in a format specifier (e.g., %,20.2f) indicates that a value should be output with a thousands separator. If false explain why.

Back 12

t

Front 13

T/F To test for a range of values in a switch statement, use a hyphen (-) between the start and end values of the range in the case label. If false explain why.

Back 13

f The switch statement does not provide a mechanism for testing ranges of values, so every value that must be tested should be listed in a separate case label.

Front 14

T/F Listing cases consecutively with no statements between them enables the cases to perform the same set of statements. If false explain why.

Back 14

t

Front 15

Write a java statement that calculates and stores (in a variable named result), the value of 2.5 raised to the power of 3, using the pow method.

Back 15

double result = Math.pow(2.5, 3);

Front 16

Match the following format specifiers with their proper type: %s

Back 16

String

Front 17

Match the following format specifiers with their proper type: %d

Back 17

integer

Front 18

Match the following format specifiers with their proper type: %f

Back 18

floating point number

Front 19

Match the following format specifiers with their proper type: %n

Back 19

new line
