![]() The answer to that is super simple, though, as it is fully determined by what you want to check for the switch variable. ▚Labels vs PatternsĪfter that excursion into switch vs if, let's get back to when to use what form of switch. In Java, the switch statement is used for executing one statement from multiple conditions. ![]() The switch statement successively checks the value. It communicates that much more clearly than an if- else- if chain and so I hope to some day see it being used in all such situations. A Java switch statement is a multiple-branch statement that executes one statement from multiple conditions. Here's a bunch of possibilities for this value - pick one and compute. Points to remember while using Switch Case. I gave num+2, where num value is 2 and after addition the expression resulted 4. With switch becoming more powerful, my guess is that it will start to eat into the use cases for longer if- else- if chains.Īnd it makes sense because that's the core tenet of switch: Explanation: In switch I gave an expression, you can give variable also. Below are some examples to show working of Enum with Switch statement. In contrast to if-then and if-then-else statements, the Java switch statement has several execution paths. We can use Enum in Switch case statement in Java like int primitive. ![]() translate `number`, then `callMethod` with it // as switch statement switch (number ) Īgain, this could be an if- else- if chain instead, but again I think the switch comes out ahead (for the same reasons as above). The Java switch case statement is a type of control-flow statement that allows the value of an expression or variable to change the control flow of program execution through a multi-way branch.
