in class Throwable
public void printStackTrace()
Throwable
System.err
. The first line of output
is the result of Throwable.toString()
, and the remaining lines represent
the data created by Throwable.fillInStackTrace()
. While the format is
unspecified, this implementation uses the suggested format, demonstrated
by this example:public class Junk { public static void main(String args[]) { try { a(); } catch(HighLevelException e) { e.printStackTrace(); } } static void a() throws HighLevelException { try { b(); } catch(MidLevelException e) { throw new HighLevelException(e); } } static void b() throws MidLevelException { c(); } static void c() throws MidLevelException { try { d(); } catch(LowLevelException e) { throw new MidLevelException(e); } } static void d() throws LowLevelException { e(); } static void e() throws LowLevelException { throw new LowLevelException(); } } class HighLevelException extends Exception { HighLevelException(Throwable cause) { super(cause); } } class MidLevelException extends Exception { MidLevelException(Throwable cause) { super(cause); } } class LowLevelException extends Exception { }
HighLevelException: MidLevelException: LowLevelException at Junk.a(Junk.java:13) at Junk.main(Junk.java:4) Caused by: MidLevelException: LowLevelException at Junk.c(Junk.java:23) at Junk.b(Junk.java:17) at Junk.a(Junk.java:11) ... 1 more Caused by: LowLevelException at Junk.e(Junk.java:30) at Junk.d(Junk.java:27) at Junk.c(Junk.java:21) ... 3 more
printStackTrace

public void printStackTrace(PrintStream out)
Throwable
Throwable.printStackTrace()
for the sample format.

out
- the PrintStream to write the trace topublic void printStackTrace(PrintWriter out)
Throwable
PrintWriter
.
The actual output written is implemention specific. Use the result of
getStackTrace()
when more precise information is needed.
This implementation first prints a line with the result of this
object's toString()
method.
Then for all elements given by getStackTrace
it prints
a line containing three spaces, the string "at " and the result of calling
the toString()
method on the StackTraceElement
object. If getStackTrace()
returns an empty array it prints
a line containing three spaces and the string
"<<No stacktrace available>>".
Then if getCause()
doesn't return null it adds a line
starting with "Caused by: " and the result of calling
toString()
on the cause.
Then for every cause (of a cause, etc) the stacktrace is printed the
same as for the top level Throwable
except that as soon
as all the remaining stack frames of the cause are the same as the
the last stack frames of the throwable that the cause is wrapped in
then a line starting with three spaces and the string "... X more" is
printed, where X is the number of remaining stackframes.
