How can I get the current stack trace in Java?

Question

How do I get the current stack trace in Java, like how in .NET you can do Environment.StackTrace?

I found Thread.dumpStack() but it is not what I want -

Answer 1

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

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

Answer 2

You can use Apache's commons for that:

String fullStackTrace = org.apache.commons.lang3.exception.ExceptionUtils.getStackTrace(e);

Answer 3

I suggest that

  Thread.dumpStack()

is an easier way and has the advantage of not actually constructing an exception or throwable when there may not be a problem at all, and is considerably more to the point.

Answer 4

try {
}
catch(Exception e) {
    StackTraceElement[] traceElements = e.getStackTrace();
    //...
}

or

Thread.currentThread().getStackTrace()

Answer 5

StackTraceElement[] stackTraceElements = Thread.currentThread().getStackTrace();

The last element of the array represents the bottom of the stack, which is the least recent method invocation in the sequence.

A StackTraceElement has getClassName(), getFileName(), getLineNumber() and getMethodName().

loop through StackTraceElement and get your desired result.

for (StackTraceElement ste : stackTraceElements ) 
{
    //do your stuff here...
}

Answer 6

I used answers from above and added formatting

public final class DebugUtil {

    private static final String SEPARATOR = "\n";

    private DebugUtil() {
    }

    public static String formatStackTrace(StackTraceElement[] stackTrace) {
        StringBuilder buffer = new StringBuilder();
        for (StackTraceElement element : stackTrace) {
            buffer.append(element).append(SEPARATOR);
        }
        return buffer.toString();
    }

    public static String formatCurrentStacktrace() {
        StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
        return formatStackTrace(stackTrace);
    }
}
