Java yield

• The keyword “yield” in Java is used in switch expressions to provide a returned value
• The “yield” keyword allows you to exit a switch expression by returning a value, which becomes the value of the switch expression.

Example:

String number = switch (number) {
    case 1:
        yield "one";
    case 2:
        yield "two";
    default:
        yield "Zero";
}
