In traditional procedural languages, you would write a long switch statement, with the different possible cases defined.switch: (employee.type) { case: Employee return employee.salaryToDate; case: FullTimeEmployee return employee.salaryToDate + employee.bonusToDate ... If you add a new kind of...
Let’s take another example of a switch statement without a default case. switch(dayOfWeek) {case"Sunday": System.out.println("It’s Sunday!");break;case"Monday": System.out.println("It’s Monday!");break;case"Tuesday": System.out.println("It’s Tuesday!");break;case"Wednesday": Syst...
It also allows you to cast this object simultaneously and implicitly to the target type. You can also combine the switch statement with record patterns to access the record fields directly, as in the case of the Point record.The following two enhancements were added in Java 20 with the ...

Create subclasses to override methods with faster versions. Avoid expensive constructs and data structures, e.g. one-dimensional array is faster than a two-dimensional array. Use the faster switch bytecode. Use private and static methods, and final classes, to encourage inlining by the compiler....
