Getting the details from a Stackktrace


Java code can throw exceptions. This comes in the form of the Stacktrace. When this happens you want to be able to get some more details. The example below shows how this can be achieved.

try {
    // My code
} catch (Throwable e) {
    // Get the stack trace
    StackTraceElement stack[] =

    // stack[0] contains the method that created
    // the exception.
    // stack[stack.length-1] contains the oldest
    // method call.
    // Enumerate each stack element.
    for (int i=0; i<stack.length; i++) {
        String filename = stack[i].getFileName();
        if (filename == null) {
            // The source filename is not
            // available
        String className =
        String methodName =
        boolean isNativeMethod =
        int line = stack[i].getLineNumber();
