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);
}
}
Here is how you can give it a try - Compile a JDK12 preview feature with Maven
