Editing Java syntax (section)

=====<code>switch</code> expressions=====

Since Java 14 it has become possible to use switch expressions, which use the new arrow syntax:

<syntaxhighlight lang="java">
var result = switch (ch) {
    case 'A' -> Result.GREAT;
    case 'B', 'C' -> Result.FINE;
    default -> throw new ThisIsNoGoodException();
};
</syntaxhighlight>

Alternatively, there is a possibility to express the same with the <code>yield</code> statement, although it is recommended to prefer the arrow syntax because it avoids the problem of accidental fall throughs.

<syntaxhighlight lang="java">
var result = switch (ch) {
    case 'A':
        yield Result.GREAT;
    case 'B':
    case 'C':
        yield Result.FINE;
    default:
        throw new ThisIsNoGoodException();
};
</syntaxhighlight>
