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 jstack utility if you want to check the current call stack of your process.

Usage:
    jstack [-l] <pid>
        (to connect to running process)
    jstack -F [-m] [-l] <pid>
        (to connect to a hung process)
    jstack [-m] [-l] <executable> <core>
        (to connect to a core file)
    jstack [-m] [-l] [server_id@]<remote server IP or hostname>
        (to connect to a remote debug server)

Options:
    -F  to force a thread dump. Use when jstack <pid> does not respond (process is hung)
    -m  to print both java and native frames (mixed mode)
    -l  long listing. Prints additional information about locks
    -h or -help to print this help message

Answer 2

Thread.currentThread().getStackTrace();

is fine if you don't care what the first element of the stack is.

new Throwable().getStackTrace();

will have a defined position for your current method, if that matters.

Answer 3

Getting stacktrace:

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

Printing stacktrace (JAVA 8+):

Arrays.asList(ste).forEach(System.out::println);

Printing stacktrage (JAVA 7):

StringBuilder sb = new StringBuilder();

for (StackTraceElement st : ste) {
    sb.append(st.toString() + System.lineSeparator());
}
System.out.println(sb);
