Feb 17, 2015 · How would I return the values that I found in this switch statement to the rest of the class for use (I want to use oneTotal, twoTotal, etc. out side of that switch statement)? Here is the code for the switch statement: switch(itemNo){ case 1: double oneTotal = 2.98 * userQuantity; return oneTotal; case 2: double twoTotal = 4.50 * userQuantity;

Jul 31, 2013 · The rules of Java require that all paths through a value-returning function encounter a return statement. In your case, even though you know the value of i will always be of a value that will cause a return from the switch, the Java compiler isn't smart enough to determine that.

If it's Java 14+, you may use functional expression of switch like this: return switch(region) { case "us-east-1" -> Region.US_EAST_1; default -> Region.US_EAST_1; };

Apr 11, 2025 · The switch statement in Java is a multi-way branch statement. In simple words, the Java switch statement executes one statement from multiple conditions. It is an alternative to an if-else-if ladder statement.

Instead of writing many if..else statements, you can use the switch statement. The switch statement selects one of many code blocks to be executed: This is how it works: The switch expression is evaluated once. The value of the expression is compared with the values of each case. If there is a match, the associated block of code is executed.

Explore Java Switch Expressions, introduced in newer versions of Java, which allow you to return a value from a switch statement. Learn how to use the case L -> label and the yield statement to return values, improving the flexibility of switch statements.

In Java, the switch statement can be used to choose different code blocks to execute based on the value of an expression. You can use a return statement within the switch statement to terminate it and return a value.

Dec 28, 2021 · Java 17 has come up with some cool features for the language, one of which is switch expressions. Maybe someone wonders, – But, does the switch already exists in Java? and the answer is yes, as a statement that only evaluates a data but does not return a value.

Java 14 adds a new form of switch label “case L ->” which allows multiple constants per case and returns a value for the whole switch-case block so it can be used in expressions (switch expressions). And the yield keyword is used to return value from a switch expression.

You use break to break out of a loop or a switch statement. You use return in a function to return a value. Return statement ends the function and returns control to where the function was called.
