Java Switch Statement Flashcards

Vocabulary flashcards reviewing core concepts, syntax, and behaviors of the Java Switch Statement.

Java Switch Statement

A selection control statement used in Java to execute one block of code from several possible choices based on the value of a single expression.

switch Keyword

The component of a Java switch block that evaluates the specified expression.

case Keyword

A keyword within a switch statement that represents a possible value to match against the evaluated expression.

break Statement

A control keyword that terminates the execution of the switch block after a matching case is executed.

default Clause

A section of a switch statement that executes its statements when none of the defined case values match the expression.

Fall-through

The execution behavior in Java where control continues to run into subsequent cases following a matched case because a break statement was omitted.

Rule for switch vs. if-else

Use switch to choose based on specific values, and use if-else to choose based on conditions.

Supported Switch Data Types

Discrete value types allowed in a switch statement, including integers, characters, strings, or enum values.

Switch with Multiple Cases

A switch structure where several case labels are stacked together to execute the same statement block before hitting a break.
