Java lost exception -


suppose have following method (a simplified version):

    void dosomething() {       try {         throw new exception("a");       } {         throw new exception("b");       }     }

exception message "b" caught in caller method. basically, there way of knowing exception thrown in try block if block throws exception? suppose method dosomething() cannot modified.

section 14.20.2 of jls states:

if execution of try block completes abruptly because of throw of value v, ...

...

if block completes abruptly reason s, try statement completes abruptly reason s (and throw of value v discarded , forgotten).

java must discard original exception v ("complete abruptly") , whole try-finally block "completes abruptly" s (the finally exception, "b").

there no way retrieve original try block exception "a", corresponds v in jls.

c# - How do I get the Nth largest element from a list with duplicates, using LINQ? -

i've seen in various stackoverflow answers can nth largest element in list doing var nthfromtop = items.orderbydescending().skip(n-1).first(); but wouldn't work if there no duplicates in list? if list contains duplicates, there way nth largest element (or set of elements) using linq? if not, efficient way in c#? to set of items equal nth largest item you'll need group items, order groups, , decrement n group size while n positive. when n reaches zero, you've hit group containing nth largest item. public static ienumerable<t> foo<t>(this ienumerable<t> source, int n) { return source.groupby(x => x) .orderbydescending(group => group.key) .skipwhile(group => { n -= group.count(); return n > 0; }) .first(); }
