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...
Java 12 introduced the switch expressions which can compute the value for the whole switch statement and assign its value to a variable. It is very similar to other normal Java statements. 2.1. Return value with Arrow Syntax Let us rewrite the last example, with a switch expression. Noticelin...
Decoding the Basic Syntax of Java Switch Statement The switch statement in Java is a multiway branch statement. It provides an easy way to dispatch execution to different parts of your code based on the value of an expression. Here’s the basic syntax: switch(expression){casevalue1:// code...
