Syntax: switch (expression) { case value1: // code break; case value2: // code break; ... ... default: // default statements } How does the switch-case statement work?

Unlike if-then and if-then-else statements, the switch statement can have a number of possible execution paths. A switch works with the byte, short, char, and int primitive data types.
Syntax. switch (expression) { case x: // code block break; case y: // code block break; default: // code block } This is how it works: The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed.
