发帖数: 456 | 1 Is it possible to make a dump method in Java, so that when it's called, it
will find out all the variables, methods info, even codes, then output it? I
want it to be a general method, which means the same code working for most
object. It would be better to provide the current variable value.. Are there
such method? Or is it possible?
Thanks! | T*********g

public class StackTraceExample
{
//private static final Logger logger = Logger.getLogger(StringReplace.class.
getName());
public static void main(String args[])
{
//calling a method to print stack trace further down
first();
}
public static void first()
{
second();
}
private static void second()
{
third();
}
private static void third()
{
//If you want to print stack trace on console than use dumpStack() method
System.err.println("Stack trace of current thread using dumpStack() method
");
Thread.currentThread().dumpStack();
//This is another way to print stack trace from current method
System.err.println("Printing stack trace using printStackTrace() method of
Throwable ");
new Throwable().printStackTrace();
//If you want stack trace as StackTraceElement in program itself than
//use getStackTrace() method of Thread class
StackTraceElement[] stackTrace = Thread.currentThread().getStackTrace();
//Once you get StackTraceElement you can also print it to console
System.err.println("displaying Stack trace from StackTraceElement in Java"
);
for(StackTraceElement st : stackTrace)
{
System.err.println(st);
}
}
}
