algorithm - Java build List from values of multiple Maps in a particular order -

-

suppose have list of integers in meaningful order (list1).

you have 2 map's integer keys subset of list1. there no overlap between 2 maps, between them both may possible list1 proper superset of set of both of keysets (i.e., there integers in list1 missing both maps).

how can build new list of objects 2 maps in objects appear in order integer key appears in list1?

you can loop:

map map1; map map2; list list2; // iterate through of possible keys in order for(object possiblekey: list1) {     // if possible ke key in 1 of maps,     // add new list.  preserve order.     if(map1.containskey(possiblekey))         list2.add(map1.get(possiblekey));     else if (map2.containskey(possiblekey))         list2.add(map2.get(possiblekey)); }

the above code simplified, should general idea.

java - SNMP4J General Variable Binding Error -

-
i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

Determine if a XmlNode is empty or null in C#? -

-
the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
