Switch Statement

In Java, the switch statement is a control flow construct that allows you to select one of many code blocks to be executed based on the value of an expression. It provides an alternative to a long series of if-else statements when you have multiple conditions to check.

Syntax

Description

1. The switch statement begins with the keyword switch, followed by an expression enclosed in parentheses. This expression is often referred to as the "selector" or "switch variable.".
2. After the opening curly brace. you define individual cases using the case keyword, followed by a constant value or expression that represents a specific case to be matched.
3. Each case block consists of one or more statements that will be executed when the corresponding case matches the value of the selector expression. The statements within each case block are typically indented for readability.
4. At the end of each case block, it's essential to include the break statement to exit the switch block. Without the break statement, execution will continue to the next case, which may not be the desired behavior.
5. Optionally, you can include a default case, which is executed when none of the previous cases match the value of the selector expression. It acts as a fallback option when no specific case matches.
6. The closing curly brace marks the end of the switch statement.
