Class StackWalkerExamples

java.lang.Object
net.jrodolfo.java_evolution.java09.StackWalkerExamples
public class StackWalkerExamples extends Object
Demonstrates StackWalker, introduced in Java 9.

Before Java 9, stack inspection commonly used Thread.currentThread().getStackTrace(), which eagerly created an array and gave limited control over how frames were consumed.

StackWalker solves this by providing a lazy and structured way to inspect stack frames. It is useful for diagnostics, logging, and framework code that needs caller information without eagerly materializing the whole stack.
