i'm having lot of trouble finding running time of following algorithm. thank if me solve explicitly line per line corresponding cost , amount of times executed. biggest problem calculating amount of times while-loop executed. algo: (a,n) tmp = 0; ready = 0; = n-1 1 if a[i-1]>a[i] temp=a[i-1]; a[i-1] = a[i]; a[i] = tmp; ready = 1; = 1 n-1 if a[i-1]>a[i] temp=a[i-1]; a[i-1] = a[i]; a[i] = tmp; ready = 1; while ready = 1; thank much the worst case bubble sort o(n^2). the problem bubble sort n times iterate whole array. the amount of times , rest sounds home me.

i have jframe main window wich has register button on in.click register button , jdialog windows pops out. public void mouseclicked(mouseevent e) { reg new1=new reg(users); new1.setvisible(true); } the jdialog window has 2 buttons->register,cancel.both of them must , close dialog window. this tried. in reg(dialog window)---> btncancel: public void mouseclicked(mouseevent e) { dialog.dispose(); system.out.println("reg disposed cancel button"); } this closes d window when run d window guess when executed main window(button clicked) still exists object in main fraim"class" , doesn't close.what should ?how make close ? you need way frame determine how dialog closed // why using `mouselistener` on buttons?? // user use keyboards to, use actionlistener instead public void mouseclicked(mouseevent e) { reg new1=new reg(users)...

let's have 4 strings. private string string_1, string_2, string_3, string_4; then let's have loop. how can access variable name index of loop? here's idea of i'm talking about: for(int = 0; < 4; i++) { string_ + = "hello, world! " + i; } i understand doing above not compile. thanks help. you can't you're asking - @ least directly. you start putting strings array , work array. string[] strings = new [] { string_1, string_2, string_3, string_4, }; for(int = 0; < 4; i++) { strings[i] = "hello, world! " + i; } console.writeline(string_3); // != "hello, world! 2" console.writeline(strings[2]); // == "hello, world! 2" but original string_3 unchanged, although slot in array correct. you can go 1 step further , way: action<string>[] setstrings = new action<string>[] { t => string_1 = t, t => string_2 = t, t => string_3 = t, t =...

i have homework problem asking asymptotic worst case of comparisons merge-sort when sorting 0s , 1s. this confusing me because looks merge-sort has same number of comparisons whatever placed in n elements. don't understand merge-sort. can enlighten me? the worst case according me when 0's , 1's come alternatively , when total number of elements factor of 4. because merging takes max time because of this. way merge sort has o(nlogn)

please explain how different collection used under different scenario. by mean how can differentiate when use list , set or map interface. please provide links examples can provide clear explanation. also if insertion order preserved should go list. if insertion order not preserved should go set. what "insertion order preserved" means? insertion order insertion order preserving order in have inserted data. for example have inserted data {1,2,3,4,5} set returns {2,3,1,4,5} while list returns {1,2,3,4,5} .//it preserves order of insertion when use list, set , map in java 1) if need access elements using index, list way go. implementation e.g. arraylist provides faster access if know index. 2) if want store elements , want them maintain order on inserted collection go list again, list ordered collection , maintain insertion order. 3) if want create collection of unique elements , don't want duplicate choose set implementation e....

i met problem using shared contexts: i have 2 threads , each has 1 context, thr1(thread1) ctx1(context1) , thr2 , ctx2. ctx2 created sharing ctx1. then, in thr2, create textures ctx2 current context, , rendering. after that, destroy ctx2 , finish thr2. now problem arised: after destroy ctx2, textures created under ctx2 not released(some of then, not all). use gdebugger profile program, , see that, these textures not released, , listed under ctx1. as repeat create thr2/ctx2 , create textures , destroy thr2/ctx2, textures getting more , more, memory. what have tried: delete textures in thr2 before destroy ctx2; in thr2 make ctx1 current , try delete textures, before ctx2 destroy; this sounds expected behavior. to explain lifetime of objects multiple contexts, i'm going use word "pool" describe collection of textures. don't think there's universal terminology concept, anything. while may picture textures being owned context, in fact own...

how serialization tool(i.e. hessian) deserialize class of different version same serialversionuid ? in cases, can skip unknown(not found in class loader) fields , keep compatible. last time, tried appending new field of map<string, object> , put unknown object map, threw classnotfoundexception . why can't skip map others? is problem associated tool's implementation or serialization mechanism? this depend on tool itself. serialversionuid intended use java's built-in serializer ( objectoutputstream ) which, best can tell reading hessian source, not used hessian. for hessian specifically, best source can find mentions these kinds of changes this email : at least hessian, it's best think of versioning set of types of changes can handled. specifically hessian can manage following kinds of changes: 1) if add or drop field, side doesn't understand field ignore it. 2) field type changes possible, if hessian can convert...

i'm building cordova app, i'd rather not use default popups such spinner happens when focus on <select></select> (i'll make own dropdown works in mobile) , want build own numpad when focus on textarea (which i'll make div pops own numpad), not use ios keyboard. basically, don't want use of native controls popup. instead want in html. is there in user experience guidelines can't when submitting app store? as far know there nothing permitts send such apps store. apple has guideline developers/designers. recommend you, have it. can find here: apple design guidelines - ui elements . doesn't say, apple allows that. every app submit store reviewed. if apple permitts said (html/css) think native keyboard fits needs. since ios8 possible build "own" keyboard need it. don't know how implement cordova application. have on here 16 keyboards build ios8: 16 great ios8 keyboards
