can anybody tell me the code is it true? why i get the int deep =12? I print out the StackTrace use for-each : java.lang.Thread.getStackTrace(Thread.java:1559) com.codegym.task.task09.task0905.Solution.getStackTraceDepth(Solution.java:13) com.codegym.task.task09.task0905.Solution.main(Solution.java:10) sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) java.lang.reflect.Method.invoke(Method.java:498) If i print out StackTrace by .getMethodName() : getStackTrace getStackTraceDepth main invoke0 invoke invoke invoke callMainMethod execute execute main main

package com.codegym.task.task09.task0905; /* In the blue depths of the stack trace… */ public class Solution { public static void main(String[] args) throws Exception { int deep = getStackTraceDepth(); } public static int getStackTraceDepth() { StackTraceElement[] ste = Thread.currentThread().getStackTrace(); for(StackTraceElement elements : ste){ System.out.println(elements.getMethodName()); } return ste.length; } }

Task conditions say that the getStackTraceDepth() method should output the stacktraces length, not the stacktrace itself. you need to do 3 things... 1. get the length of the stacktrace 2. output that int 3. return that int

I post the stacktrace details because i run the code in getStackTraceDepth() method public class Solution { public static void main(String[] args) throws Exception { int deep = getStackTraceDepth(); } public static int getStackTraceDepth() { StackTraceElement[] ste = Thread.currentThread().getStackTrace(); return ste.length; } } It will output int deep = 12 . anybody can tell me what is the problem in my code ? or the web site have bug?

that program outputs nothing at all if I try it... as already said (because required by CG) add code to the getStackTraceDepth() method that outputs the stacktrace arrays length.

int steDepth = Thread.currentThread().getStackTrace().length;
System.out.println(steDepth);
return steDepth;

I have run your code in getStackTraceDepth() method , it will output int steDepth = 12. public static int getStackTraceDepth() { int steDepth = Thread.currentThread().getStackTrace().length; System.out.println(steDepth); return steDepth; }

You probably run that code in the codegym online editor or the app. Here my guess is, that your code is executed by an already running java program, name it validator. And that program also adds methods to the stacktrace. Use an IDE like IntelliJ or if you think that this is to heavy, just use your PCs default editor.
