can tell me what's wrong java code? array : static string [][] data = new string[6][2]; in case, data[0][1]="abcd" , data[1][1]="efgh" , remaining data[2-5][1] should null . trying print out non- null ones. @ (j=2,k=3) , code doesn't executed after that. eg, "i here3" doesn't printed. int k=1; system.out.println("data[2][0]="+data[2][0]); for(int j=0; j<data.length; j++,k++) { system.out.println("j="+j+" k="+k); if (!(data[j][0].equals("null"))) { system.out.println("i here2"); sbissues = sbissues.append("\n"); sbissues = sbissues.append(k); sbissues = sbissues.append(".

what ob means in following code - same item? foreach (var item in allitems) { if (excludeitems.exists(ob => ob.equals(item))) { console.writeline("item {0} excluded",item); } } ob parameter lambda expression . if you're familiar anonymous methods, it's like: foreach (var item in allitems) { if (excludeitems.exists(delegate (string ob) { return ob.equals(item); }) { console.writeline("item {0} excluded",item); } } that's assuming type of ob should string - may not be. depend of excludeitems , due generic type inference. lambda expressions can more explicit, could written as: if (excludeitems.exists((string ob) => { return ob.equals(item); }) or if (excludeitems.exists((string ob) => ob.equals(item)) basically there several little shortcuts in lambda expressions common case of single parameter type can inferred, , return value single expression. now in particular case, dele...

i trying use function histogram plot density of data. sample format of data follows: library(lattice) index<-c(1,1,1,2,2,2,2) freq<-c(3,4,6,3,6,2,2) d<-data.frame(index,freq) histogram(~d$freq|d$index) i want have index number printed strip text each histogram (i.e. in example, 1 , 2 on top of histograms respectively instead of printed d$index ), don't know of easy way (i know have use strip.custom() possibly, , change var.name properly, don't know how iterate on according index) if change index variable factor supposed default behavior, i.e. printing shingle levels in strip: library(lattice) index<-factor(c(1,1,1,2,2,2,2)) freq<-c(3,4,6,3,6,2,2) d<-data.frame(index,freq) histogram(~d$freq|d$index) just fun can play style variable in strip.default: histogram(~freq|index, data=d, strip = function(..., style){ strip.default(..., style = 4)} )

i'm running java application windows service , using java application, executed user, set directory used windows service application. is there way in java determine file permissions of directory user? in case, want know file permissions of windows service application while running separate java application executed user. this kind of filesystem support not available in standard java, because java cross-platform , filesystem security differs across platforms (or may not exist @ all). however, there plans add support java 7 (which have been waiting years get!) if using on windows , know c/c++, can use jni (java native interface) jna tap windows dlls , information. otherwise, can trial or paid version of jniwrapper works out-of-the-box. i'm not sure if provides support file security, provide other filesystem support - you'll need review feature list.

can explain me how 64 bit applications, 64bit os, , 64 bit cpu fit establish how memory addressable application? for example, how addressable memory application affected if run 64bit application on 64bit cpu, 32bit os? or 64bit cpu 64bit os , 32bit application? what happens when run 64bit application on 32bit cpu? you can't run 64-bit application on 32-bit cpu/os. a 64-bit os running on 64-bit processor has unlimited memory. address space 0 2^64, or 18.4 exabytes. a 32-bit application running on 64-bit os/processor gets 32-bit address space, 4gb. more detail: http://cnx.org/content/m13082/latest/

so delved singleton classes , yes, find them quite helpful. use singletons data storage multiple targets (views, tables etc.). being said, can see myself going implement lot of singletons in project. but can lot of singletons have negative impact? i've read singletons create 1 instance each of them in proces. other class instances released (assuming released properly) memory, should singletons released too? so narrow down 1 question: harmful have lot of singletons? singletons don't scale. no matter think should singleton, when system gets bigger, turns out needed more one. if never need more one, singleton fine. however, systems scale, typically need more 1 of anything within own context. singletons merely way "global". it's not bad, generally, it's not idea systems evolve , grow in complexity.
