Weird Java Exception name -

i did system.out.print object null , got this:

550270261027054028026002805302902590290520300258030051031025703105003202560320 490330255033048034025403404703502530350460360252036045037025103704403802500380 43039024903904204002480exception 

i tried googling name of exception long.

does know exception means?

for (int = bulletlist.size(); > 0; i--) {         final bullet b = bulletlist.get(i - 1);/* bullet class containing it's image, position , rectangle , handling movement*/         b.r = new rectangle(b.x, b.y, 34, 20);         (i = obsticallist.size(); > 0; i--) {             final obstical o = obsticallist.get(i - 1);//obsical class bullet class stationary thing             system.out.print(o.r.x);             system.out.print(b.r.x);//this exception         }      }    3202452730245310255272025530026527102652902752700exception in thread "thread-3"     @ startingclass.checkcollision(startingclass.java:175)     @ startingclass.run(startingclass.java:107)     @ java.lang.thread.run(unknown source) 

the digits aren't part of exception name. code printing digits no line feeds standard out.

the default exception handler prints stack trace standard error. messages standard output , standard error being interleaved on console, digits see code, , "exception" fragment of stack trace.

most likely, if further in console, you'll see beginning of exception name. runtime exception line indicate throw nullpointerexception, if b or b.r null; but, given code, doesn't possible. maybe exception thrown line. line numbers , stack trace pin down, perhaps it's nullpointerexception previous line.
