Java Control Structure

Front 1

Structured statements that allow programmers to change the way statements in a program is executed.

Back 1

Java Control Structures

Front 2

Give the Types of Java Control Structures.

Back 2

> Decision Control Structures

> Repetition Control Structures

Front 3

Allows control over specific sections of code to be executed.

Back 3

Decision Control Structures

Front 4

Allow repeated execution of specific sections of code.

Back 4

Repetition Control Structures

Front 5

A statement that specifies statements or blocks of code that will be executed if and only if a conditional statement returns are required Boolean value.

Back 5

If Structure

Front 6

Can execute a statement when a condition returns a required Boolean value, but will also execute a different statement if the condition does not return a required value.

Back 6

If-Else Structure

Front 7

Used when more than two conditional statements are involved.

Back 7

If-Else-if Structure

Front 8

Allows Java to "switch" between statements based on a given expression or condition.

Back 8

Switch Structure

Front 9

What are the differences between switch and if?

Back 9

> Multiple statements can be executed without braces.

> When a case in the switch statement has been matched, statements for the matched case and succeeding statements are executed.

The structure cannot be used for ranged values.

Front 10

Structured statements that allow programmers to repeatedly execute certain blocks of code.

Back 10

Repetition Control Structures

Front 11

Basic repetition control structure that repeats statements as a conditional statement is being satisfied.

Back 11

While Structure

Front 12

Evaluates the conditions at the beginning of the statement.

Back 12

While Structure

Front 13

Evaluates the conditions at the end of the structure.

Back 13

Do-While Structure

Front 14

Provides a compact way to iterate over a range of values used in loops.

Back 14

For Structure

Front 15

Statements that specifically dictate the flow of control within a program.

Back 15

Branching Statements

Front 16

Causes the termination of a loop or initiate an exit from a decision control structure.

Back 16

Break

Front 17

Exits the current method, statement or control structure and returns a value.

Back 17

Return

Front 18

Back 18

Front 19
