i have simple java project, has file input.java. code input.java goes - package com.src.functionalities; import java.util.scanner; public class input { public static void main(string[] args) { // todo auto-generated method stub scanner reader = new scanner(system.in); // reading system.in system.out.println("enter number: "); int n = reader.nextint(); // scans next token of input int. system.out.println("you have provided : " + n); } } now, have created executable jar file in eclipse export -> jar -> executable jar file , named jar file test.jar. now, when try open via command prompt, works fine. java -jar test.jar but, expecting open command prompt when double click on runnable jar file. problem here? thanks! that because jvm expects app have gui, app strictly console app. if don't have gui, nothing happens, since jvm not invoke windows console. either make batch file j...

i have, believe, relatively common use case spark streaming: i have stream of objects filter based on reference data initially, thought simple thing achieve using broadcast variable : public void startsparkengine { broadcast<referencedata> refdatabroadcast = sparkcontext.broadcast(getrefdata()); final javadstream<myobject> filteredstream = objectstream.filter(obj -> { final referencedata refdata = refdatabroadcast.getvalue(); return obj.getfield().equals(refdata.getfield()); } filteredstream.foreachrdd(rdd -> { rdd.foreach(obj -> { // final processing of filtered objects }); return null; }); } however, albeit infrequently, my reference data change periodically i under impression modify , re-broadcast variable on driver , propagated each of workers, broadcast object not serializable , needs final . what alternatives have? 3 solutions can think of are: move reference...

from signalr wiki there section on reconnecting event reconnecting client event. raised when (a) transport api detects connection lost, or (b) keepalive timeout period has passed since last message or keepalive ping received. signalr client code begins trying reconnect. can handle event if want application take action when transport connection lost. the default keepalive timeout period 20 seconds. the section on timeouts tells 3 configuration values i.e. disconnecttimeout,keepalive & connectiontimeout. my question is, if want decrease keepalive value say, 5 seconds or increase say, 30 seconds, keep alive timeout, after client starts reconnect change automatically or still default 20 seconds mentioned above? if no, there way set keep alive timeout via code?

i got comment question form tobia tesan can't msg in here. php echo vs return, way better? he suggest me change <span class="wuuk_time"> instead of using <b> , you'll define in css file, achieving separation of database logic, output logic , presentation/styling. first, bad using <b> ? second, how separation of database logic, output logic , presentation/styling? use css. not separation of logic , output? it's matter of 'best practices'. avoiding inline styling, such use of <b> tag done improve readability. can reuse class "wuuk_time" throughout html later, see fit. moreover, if change styling italicized instead of bold example, easier change "wuuk_time" class reflect desired changes throughout webpage opposed hunting down individual <b> tags in html. readability, maintainability.

i learning c language, , school put assignments on myth, every time have log in ssh , execute command remotely. want download files , execute them on own macbook. when use make command compile files, got errors , warnings such : gcc -g -o0 -std=gnu99 -wall $warnflags -m32 -c -i. vectest.c -o vectest.o warning: unknown warning option '-wlogical-op'; did mean '-wlong-long'? vectest.c:10:10: fatal error: 'error.h' file not found #include <error.h>” i googled these problems not find satisfactory answer. can me solve ? or have use linux machine instead? indeed; compilers various platforms (even if it's "same" compiler, such gcc) may have different flags , behaviors. may able work - remove -wlogical-op flag $warnflags in makefile , if error.h file system-supplied header file, you're in trouble. therefore, suggest download e.g. virtualbox , run linux on it.

i'm learning greedy algorithms , came across problem i'm not sure how tackle. given set of intervals (a,b) start time , end time b, give greedy algorithm returns minimum amount of intervals overlap every other interval in set. example if had: (1,4) (2,3) (5,8) (6,9) (7,10) i return (2,3) , (7,8) since these 2 intervals cover every interval in set. have right this: sort intervals increasing end time push interval smallest end time onto stack if interval (a,b) overlaps interval on top of stack (c,d) (so less d) if a<=c keep (c,d). else update interval on top of stack (a,d) if interval (a,b) not overlap interval on top of stack (c,d) push (a,b) onto stack at end stack contains desired intervals , should run in o(n) time my question is: how algorithm greedy? i'm struggling concepts. maybe have right , maybe don't, if do, can't figure out greedy rule is/should be. edit: valid point made below, should have been clearer about. (7,8) works instead of ...
