The switch statement in Java is used to select one of many code blocks to be executed:switch (variableToBeSwitched). It’s a powerful tool for controlling the flow of your code, especially when you have multiple conditions to handle. Here’s a simple example: intday=3;switch(day){case1:...

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...
statements help in providing multiple possible execution paths for a program. Java switch statements can be used in place of if-else statements to write more cleaner and concise code. Java switch statements have evolved over time. In this tutorial, we will learn about basic switch statement … ...
The switch statement evaluates an expression. The value of the expression is then compared with the values of each case in the structure. If there is a match, the associated block of code is executed. The switch statement is often used together with a break or a default keyword (or both)...
The switch statement allows us to execute a block of code among many alternatives. In this tutorial, you will learn about the switch...case statement in Java with the help of examples.
