Using two values for one switch case statement

Question

In my code, the program does something depending on the text entered by the user. My code looks like:

switch (name) {
        case text1: {
            //bla         


        

Answer 1

With the integration of JEP 325: Switch Expressions (Preview) in JDK-12 early access builds, one can now make use of the new form of the switch label as :-

case text1, text4 -> {
     //blah
} 

or to rephrase the demo from one of the answers, something like :-

public class RephraseDemo {

    public static void main(String[] args) {
        int month = 9;
        int year = 2018;
        int numDays = 0;

        switch (month) {
            case 1, 3, 5, 7, 8, 10, 12 ->{
                numDays = 31;
            }
            case 4, 6, 9, 11 ->{
                numDays = 30;
            }
            case 2 ->{
                if (((year % 4 == 0) &&
                        !(year % 100 == 0))
                        || (year % 400 == 0))
                    numDays = 29;
                else
                    numDays = 28;
            }
            default ->{
                System.out.println("Invalid month.");

            }
        }
        System.out.println("Number of Days = " + numDays);
    }
}
