2. Pattern Matching for Switch (Preview)

Pattern matching for switch simplifies conditional logic, improving code readability. It allows a more concise way to check types.

Benefits:

●?????? Reduces boilerplate code.

●?????? Improves readability and maintainability.

●?????? Makes switch cases more expressive.

?

switch (obj) {

??? case String s -> System.out.println("String: " + s);

??? case Integer i -> System.out.println("Integer: " + i);

??? default -> System.out.println("Other: " + obj);

}

3. Strong Encapsulation of JDK Internals

Java 17 enforces stricter access to internal APIs, reducing reliance on deprecated or unsupported code, ensuring more stable and secure applications.

Impact:

●?????? Minimizes internal API usage.

●?????? Encourages best practices.

●?????? Leads to future-proof code.
