YieldStmt Statement

YieldStmt Entity

In Java, the yield keyword is used within switch expressions to return a value from a case label. It was introduced in Java 13 as part of switch expressions to provide a way to return values from individual cases. Unlike the traditional break statement, yield allows you to produce a value that becomes the result of the entire switch expression. This is particularly useful when you need to compute and return different values based on different cases in a more concise and expressive way than traditional switch statements.

Example

String message = switch (number) {
    case ONE -> {
        yield "Got a 1";
    }
    case TWO -> {
        yield "Got a 2";
    }
    default -> {
        yield "More than 2";
    }
};
