Print Full Call Stack on Printstacktrace()

Print full call stack on printStackTrace()?

here is an explanation of the 'caused by' and '... n more' lines in the printed trace. see also the JavaDoc for printStackTrace. you might not have any work to do.

Note the presence of lines containing the characters "...". These lines indicate that the remainder of the stack trace for this exception matches the indicated number of frames from the bottom of the stack trace of the exception that was caused by this exception (the "enclosing" exception). This shorthand can greatly reduce the length of the output in the common case where a wrapped exception is thrown from same method as the "causative exception" is caught.

How to print full stack trace in exception?

I usually use the .ToString() method on exceptions to present the full exception information (including the inner stack trace) in text:

catch (MyCustomException ex)
{
    Debug.WriteLine(ex.ToString());
}

Sample output:

ConsoleApplication1.MyCustomException: some message .... ---> System.Exception: Oh noes!
   at ConsoleApplication1.SomeObject.OtherMethod() in C:\ConsoleApplication1\SomeObject.cs:line 24
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 14
   --- End of inner exception stack trace ---
   at ConsoleApplication1.SomeObject..ctor() in C:\ConsoleApplication1\SomeObject.cs:line 18
   at ConsoleApplication1.Program.DoSomething() in C:\ConsoleApplication1\Program.cs:line 23
   at ConsoleApplication1.Program.Main(String[] args) in C:\ConsoleApplication1\Program.cs:line 13

Java / Android - How to print out a full stack trace?

There's overrides of all the log methods with (String tag, String msg, Throwable tr) signatures.

Passing an exception as the third parameter should give you the full stacktrace in logcat.

How can I get the current stack trace in Java?

You can use Thread.currentThread().getStackTrace().

That returns an array of StackTraceElements that represent the current stack trace of a program.

how to print stack trace to stdout in java for debug?

You only need one line.

new Exception().printStackTrace(System.out);

Thanks to Get current stack trace in Java

print stack trace to stderr:

new Exception().printStackTrace();

Print the stack trace of an exception

Throwable.printStackTrace(..) can take a PrintWriter or PrintStream argument:

} catch (Exception ex) {
    ex.printStackTrace(new java.io.PrintStream(yourOutputStream));
}

That said, consider using a logger interface like SLF4J with an logging implementation like LOGBack or log4j.

How to print java method call stack?

Here is how you print the stack trace from a given location in your source file.

System.out.println("Printing stack trace:");
StackTraceElement[] elements = Thread.currentThread().getStackTrace();
for (int i = 1; i < elements.length; i++) {
     StackTraceElement s = elements[i];
     System.out.println("\tat " + s.getClassName() + "." + s.getMethodName() + "(" + s.getFileName() + ":" + s.getLineNumber() + ")");
}

Avoid printStackTrace(); use a logger call instead

It means you should use logging framework like logback or log4j and instead of printing exceptions directly:

e.printStackTrace();

you should log them using this frameworks' API:

log.error("Ops!", e);

Logging frameworks give you a lot of flexibility, e.g. you can choose whether you want to log to console or file - or maybe skip some messages if you find them no longer relevant in some environment.

Tried to print stack trace using logback but stack trace is not printing

e.toString() will just print the error message.

If you want to print the complete stacktrace , use the error method :

LOGGER.error("Exception occurred",e)

https://logging.apache.org/log4j/2.x/log4j-api/apidocs/org/apache/logging/log4j/Logger.html#error-java.lang.String-java.lang.Throwable-

If you need to extract out full stack trace , checkout the following util method from apache common :

LOGGER.info("Exception : ",ExceptionUtils.getStackTrace(e));

https://commons.apache.org/proper/commons-lang/javadocs/api-2.6/org/apache/commons/lang/exception/ExceptionUtils.html#getFullStackTrace(java.lang.Throwable)
