Pattern Matching for instanceof (introduced in Java 16)

 Pattern Matching for instanceof (introduced in Java 16)

Pattern matching simplifies code that checks types and performs casts. It allows you to combine type checking and type casting into a single operation. Here's an example:

if (obj instanceof String str) {

    System.out.println(str.length()); // Safe to access str as a String

} else {

    System.out.println("Not a string.");

}
