Pattern Matching for instanceof

 Pattern Matching for instanceof

Java 16 introduced Pattern Matching for instanceof, which provides a more concise and readable way to perform type checks and type casts. This feature allows developers to combine an instanceof check with a type cast in a single expression.

Example:

Before Java 16:

if (obj instanceof String) {

    String str = (String) obj;

    // ...

}

With Pattern Matching for instanceof:

if (obj instanceof String str) {

    // ...

}
