- switch statement
  - implements a selection control flow
  - syntax:
    switch ( <arithmetic expression> ) {
      
      <case label 1> : <case body 1>
      ...
      <case label n> : <case body n>
    }
    - case label syntax
      - one of:
        case <constant>
        - constant: either named or literal
        - no two cases can have the same constant value
        - cases can be listed in any order
        default
        - reserved word
    - case body
      - sequence of zero or more statements
      - not left and right braces
    - arithmetic expression
      - data type must be char, byte, short, int
      - value is compared against each constant value of the case labels
      - executes body if a match exists
      - if no matching case, continues after switch statement
    - break statement
      - skips the rest of the switch statement
      - without, all statements after the first match will be executed
      - not necessary in the last case
        - included in all cases by convention for consistency
    - individual cases don't have to include a statement
    - default case
      - always executed if there is no matching case
      - at most one
      - safer to always include
        - defensive programming
      - recommend always place last

Quick Check
1. It has two separate cases that test the same constant
2. It doesn't use constants for the case tests.
