The break and default keywords are optional, and will be described later in this chapterThe example below uses the weekday number to calculate the weekday name:Example int day = 4; switch (day) { case 1: System.out.println("Monday"); break; case 2: System.out.println("Tuesday"); bre...
In this example,numis 1, which matches the first case. However, because there’s no break statement after the first case, Java ‘falls through’ to the second case and executes that as well, resulting in both ‘One’ and ‘Two’ being printed. ...
