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...
However, aswitchstatement in Java traditionally works with specific values such as integers, characters, or enumerations.In recent versions of Java (Java 12 and beyond), theswitchstatement has evolved to allow for more flexible case matching, but greater-than-or-equal-to conditions are still not...

In this example, the output of the program would be “You are a Grade B Employee: Bonus = 1000.” Of course, this is a simplified example but it is a functional switch statement that could easily be adopted for more practical use in your own Java applications. ...
Switch case statement is used when we have number of options (or choices) and we may need to perform a different task for each choice. The syntax of Switch case statement looks like this – switch (variable or an integer expression) { case constant: //Ja
