exceptions in ruby

[Martin Durai]

Could any one tell me the related exception in ruby. I am in process of
porting java methods. As java uses lots of inbuilt exception its very
difficult for me to port. could any one help me to tell the related
things in ruby

ArrayIndexOutOfBoundsException
RuntimeException
XmlPullParserException
IllegalArgumentException
UnsupportedEncodingException
IndexOutOfBoundsException
IOException
EOFException
NullPointerException
ClassNotFoundException
ConcurrentModificationException (Iterators throw them)

Thanks in advance

Unfortunately a matching will not be possible, I am not sure if the
following list does you any good
but in some situations similar exceptions might be raised in Ruby, it
of course depends a lot
of how you translate, I still maintain my statement from the other
tread, Java cannot be translated to Ruby as
such, you need to rethink the code, maybe the following examples show
better what I meant:

ArrayIndexOutOfBoundsException

IndexError, but this cannot be ported easily, it is
only raised in specific situations
e.g. x=[]; x[12] -> nil

RuntimeException same name
XmlPullParserException

depends on your XML Toolkit, unlikely to find a correspondance

IllegalArgumentException ParameterError
UnsupportedEncodingException

RobertHasNoClueException_SORRY

IndexOutOfBoundsException IndexError
EOFError
NullPointerException

NoMethodError in some cases, there is no such thing
in reality, I assume that the receiver is
nil but you believe it is something else

ClassNotFoundException

depends on the context, NameError in some cases

ConcurrentModificationException (Iterators throw them) I believe there is none

Thanks in advance

ParameterError

Are you sure you didn't mean to write "ArgumentError"?

I meant to write ParameterError, of course, boldly

502/6 > irb
irb(main):001:0> ArgumentError
=> ArgumentError
irb(main):002:0> ParameterError
NameError: uninitialized constant ParameterError
from (irb):2
irb(main):003:0>

and wrongly
