Define a switch statement with the syntax: switch(expression) {}.
Inside the switch block, add case labels for each possible value of the expression.
For each case, write the code block to execute when the case matches.
Use the break statement after each case block to prevent fall-through to the next case.
Optionally, include a default case to handle unmatched values.
Example Syntax:
switch(expression) {case value1:// Code block for value1break;case value2:// Code block for value2break;default:// Code block for unmatched values}Copied!✕CopyImportant Notes:
The expression must evaluate to a compatible type (e.g., int, char, String, or enums).
Case values must be constants or literals.
The default case is optional but recommended for handling unexpected values.
