In prior versions of Java, the instanceof operator workes as follows: Object o = "asdf"; if (o instanceof String) { String s = (String) o; System.out.println(o); } Java 15 - and Java 14 as a preview feature - introduces an enhanced instanceof operator, which brings the ability to cast the eximined instance to the type of the right operand.
