facilitate the comparison. Each case keyword is supplied the value for the comparison and the line is
ended with a colon (:), which indicates the end of the case and the start of the code block to execute

following a match. If you then require a final else statement to provide the catchall clause, you use the
default keyword:
switch ( myValue )
{
case val1:
// do code
case val2:
// do code
...
default:
// if all else fails, do this
}
When a switch statement is executed, the virtual machine executing the code will compare the given
value with each case until a match is made or the end of the switch statement has been found. In many
languages, once a match is made and the relevant code for that case is executed, the next case ??™ s code
segment is executed even if the case ??™ s comparison value is not a match, and then the next, and so on
until the end of the switch block has been reached or a break keyword is found.
