It means bad programming (as does catching Exception) http://java.sun.com/j2se/1.5.0/docs/api/java/lang/Throwable.html

Take a look at the inheritance tree. Exception extends Throwable, so a catch block which is catching throwables will catch exceptions and errors. (Error do not extend Exception)Kaj

java.lang.Throwable is the parent of java.lang.Exception and java.lang.Error.

kk thanx i went thru that..wat i understood is.. if i give this Exception in the catch block then i can catch only those exceptions not the errors..so if i need to catch this error then i have to put Throwable in the catch block even its bad practise..

I have only caught Throwables 4-5 times in 10 years so it's not something which you do often.

first u need to understand the difference between exception and error as i think u are confused with them make it clear

Exceptions are caused by programs thus writing efficient program a program can control them

Error : they are not in the hand of programmers

like system failure, jvm terminates etc

please go through the document again...
