How has stack traces and debugging changed in recent Java versions?

In recent versions of Java, particularly Java 10 and later, stack traces and debugging have undergone significant improvements to enhance the developer experience. These changes include more informative stack traces, the introduction of the `StackWalker` API, and enhanced support for exception handling. Let's explore these features in detail:

1. Improved Stack Traces

Java 10 introduced a new stack trace format that provides more clarity. The lines in the stack trace now specify the lambda expressions and method references, making it easier to track where an error originated.

2. StackWalker API

The new `StackWalker` API offers a more flexible and efficient way to traverse stack frames. Developers can now filter stack traces and access deep details with ease, without the overhead of traditional stack trace mechanisms.

3. Enhanced Exception Messages

Java has improved the detail available within exceptions, allowing for better debugging. The error messages provide more contextual information, which aids in identifying and rectifying issues more rapidly.

Example Usage of StackWalker

import java.lang.StackWalker;
import java.util.Optional;

public class StackWalkerExample {
    public static void main(String[] args) {
        // Getting the StackWalker instance
        StackWalker stackWalker = StackWalker.getInstance();

        // Using StackWalker to get stack frame information
        Optional frame = stackWalker.walk(frames -> frames.findFirst());
        frame.ifPresent(System.out::println);
    }
}
