Method Detail

printStackTrace

public void printStackTrace()
Description copied from class: java.lang.Throwable
Print a stack trace to the standard error stream. This stream is the current contents of System.err. The first line of output is the result of Throwable.toString()>Throwable.toString() 55 , and the remaining lines represent the data created by Throwable.fillInStackTrace()>Throwable.fillInStackTrace() 55 . 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
 {
 }

printStackTrace

public void printStackTrace(java.io.PrintStream stream)
Description copied from class: java.lang.Throwable
Print a stack trace to the specified PrintStream. See Throwable.printStackTrace()>Throwable.printStackTrace() 55 for the sample format.


printStackTrace

public void printStackTrace(java.io.PrintWriter stream)
Description copied from class: java.lang.Throwable
Prints the exception, the detailed message and the stack trace associated with this Throwable to the given 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.
