Boost the Switch Statement in JDK 12

Boost the Switch Statement in JDK 12

Starting with JDK 12, the “switch” statement is extended so that it can be used as either a statement or an expression.

A sample:

switch (day) {    case MONDAY, FRIDAY, TUESDAY, SUNDAY - System.out.println(...);    case THURSDAY, SATURDAY              - System.out.println(...);    case WEDNESDAY                       - System.out.println(...);}
