Type inference
Potential for more pattern matching features. |
| gptkbp:example |
if (obj instanceof String s) { ... }
Used in various Java applications. Sample applications provided. Switch expressions can simplify complex conditions. Switch expressions can be nested. Switch expressions can be used with enums. Switch expressions can be used with integers. Switch expressions can be used with objects. Switch expressions can be used with strings. Switch expressions can enhance code clarity. Switch expressions can have a default case. Switch expressions can improve performance. Switch expressions can return values. Switch expressions can use multiple case labels. int result = switch (day) { case MONDAY -> 1; case TUESDAY -> 2; default -> 0; } switch (value) { case 1: yield " One"; case 2: yield " Two"; } |
