Getting the Stack Trace of an Exception

Few days back, i did some R&D on exception.printstacktrace in java. Below is the code example for that.

try {
// My code
} catch (Throwable e) {
// Get the stack trace
StackTraceElement stack[] = e.getStackTrace();
// 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 = stack[i].getClassName();
String methodName = stack[i].getMethodName();
boolean isNativeMethod = stack[i].isNativeMethod();
int line = stack[i].getLineNumber();

//Comments are welcome
