How to create few catches?
for example:
try{
  ...
}
catch(Object o){
  ...
}
catch(Exception e){
  ...
}

The syntax is ok, but catch(Exception) is never reached.
because Object will also match Exceptions.
I think the compiler will argue about that.

Always order your catches from most-derived to least-derived.  So,

try { .. }
catch(Exception e) { .. }
catch(Object o) { .. }

That's what the "catch at foo hides catch at bar" means.
