Java 14 introduced new improvements in the switch statement which makes it less verbose and easier to read. Take a look! :)

switch (day) {
case 1: System.out.println("Monday");
break;
case 2: System.out.println("Tuesday");
break;
case 3: System.out.println("Wednesday");
break;
case 4: System.out.println("Thursday");
break;
case 5: System.out.println("Friday");
break;
case 6: System.out.println("Saturday");
break;
case 7: System.out.println("Sunday");
break;
default: System.out.println("Invalid day.");
}

switch( day ) {
case 1 -> System.out.println("Monday");
case 2 -> System.out.println("Tuesday");
case 3 -> System.out.println("Wednesday");
case 4 -> System.out.println("Thursday");
case 5 -> System.out.println("Friday");
case 6 -> System.out.println("Saturday");
case 7 -> System.out.println("Sunday");
default -> System.out.println("Invalid");
}

• The switch statement can now return a value:

String output = switch (day) {
case 1 -> "Monday";
case 2 -> "Tuesday";
case 3 -> "Wednesday";
case 4 -> "Thursday";
case 5 -> "Friday";
case 6 -> "Saturday";
case 7 -> "Sunday";
default -> "Invalid";
};
System.out.println(output);

switch (month) {
case 4:
case 6:
case 9:
case 11: System.out.println("30 days");
break;
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
case 12: System.out.println("31 days");
break;
case 2: System.out.println(“28 days");
break;
default: System.out.println("No such month");
}

System.out.println(
switch(month) {
case 4, 6, 9, 11 -> "30 days";
case 1, 3, 5, 7, 8, 10, 12 -> "31 days";
case 2 -> "28 days";
default -> "No such month";
}
);
• The case selector can now have multiple values:
