Switchhas evolved over time. New supported types have been added, particularly in Java 5 and 7. Also, it continues to evolve —switchexpressions will likely be introduced in Java 12. Below we’ll give some code examples to demonstrate the use of theswitchstatement, the role of thebreakstatem...
While the switch statement in Java is a powerful tool, it can also be a source of bugs if not used correctly. Let’s discuss some of the common issues you might encounter when using the switch statement and how to solve them. Forgetting the Break Keyword One of the most common mistakes ...

Stringclass(added in Java 7) HerelabelOne,labelTwoandlabelThreeare “compile-time constant expressions” orconstants(the value of the labels must be known at compile-time). We can achieve similar functionality with a chain ofif-else blocks, but theswitchstatement is more readable and clean. ...
//statement } Flow Diagram of Switch Case Statement The above flow diagram clearly shows how the Switch and Case statement works in Java. It shows how matching the expression defined in the Switch statement is matched with the Case value starting from the top until the last steps. If the va...
Java 14 introduces a new syntax for theswitch-casestatement. Users can add multiple values for a singlecaseby separating the comma, and users have to put the executable code in the curly braces. In this section, we’ll explore the significance of arrow syntax and demonstrate how it simplifies...
