i need sorting array in alphabetical order using bubble sort algorithm. my code is: public class strings { public static void main(string[] args) { scanner reader = new scanner(system.in); string tempstr; system.out.print("enter strings > "); string s1 = new string(reader.nextline()); string[] t1 = s1.split(", "); (int t=0; t<t1.length-1; t++) { (int = 0; i<t1.length -1; i++) { if(t1[i+1].compareto(t1[1+1])>0) { tempstr = t1[i]; t1[i] = t1[i+1]; t1[i+1] = tempstr; } } } for(int i=0;i<t1.length;i++) { system.out.println(t1[i]); } } } the code compiles, not sort alphabetical. please me. you have 3 errors in code. the first error in inner loop, in place check statement, should i <...

i tried test following code, , gave me 434 on n, result did not anticipate, what's reason loss of precision? double f = 4.35; int n = (int) (100 * f); // n 434 - why? n = (int) math.round(100*f); // n 435 floating point isn't perfect. uses approximated values. in particular, double s can not represent numbers. 1/3 can't precisely represented in decimal using finite number of digits, can't 4.35 represented in binary finite number of bits. so rounded results. values close 4.35 , not quite equal. in case, it's bit smaller, when multiply 100, don't 435 , almost 435 , not quite same. when cast int , truncate result, 434,999... becomes 434 . in contrast, when use math.round , convert 434,999... 435 (which can represented precisely). if precisely representing 4.35 necessary, take @ java bigdecimal type.

i'm trying populate number of combo boxes in formload method, 1st 1 populates. in same method same stored procedures called data grids , work fine. please see attached code: private void frmmain_load(object sender, eventargs e) { dataaccesslayer dal = new dataaccesslayer(); pnleditcall.visible = false; pnleditinspection.visible = false; pnleditequipment.visible = false; #region populate datagrids dgvinspections.datasource = dal.getallinspections(); dgvcalls.datasource = dal.getallcalls(); dgvstaff.datasource = dal.getallstaff(); dgvlabs.datasource = dal.getalllabs(); dgvequipment.datasource = dal.getallequipment(); #endregion #region populate comboboxes cmbinspectionstaff.datasource = dal.getallstaff(); cmbinspectionstaff.displaymember = "name"; cmbinspectionstaff.valuemember = "[staffid]"; cmbcallstaff.datasource = dal.g...

i'm trying output java application use below code output values system.out.println(object.getnumber(3)); system.out.println(object.getnumber(4)); i'm using exec("somejavapath javaname", $output) , print_r($output) output array print. know values wanted format instead of array ( [0] => 34 ) i want this array ( [0] => 3 [1] => 4 ) does know format? thanks if not expecting comas in output java application , include coma between 2 values : system.out.println(object.getnumber(3)); system.out.println(","); // print coma in between system.out.println(object.getnumber(4)); then $values_array = explode( ',', $output );

i'm looking suggestions of portable lightweight libraries written in c++ , support mathematical , business rule expression , evaluation. understand c++ doesn't provide such functionality in stl . the basic requirement follows: the expressions evaluated comprised of numbers , strings , variables either representing numbers or strings. some of expressions expected evaluated many times per second (1000-2000 times), hence there requirement high performance evaluations of expressions. originally project @ company, encode business rules classes derived base expression class. problem approach not scale number of expressions increases. i've googled around, "libraries" find pretty simple examples of shunting yard algorithm, of expression parsers, perform parsing , evaluation in same step making them unsuitable continuous reevaluations, , support numbers. what i'm looking for: library written in c++ (c++03 or c++11) stable/production worthy ...

i using code store html code in variable called $conversions $conversions = "gbp " . number_format($file*0.84) . "chf " . number_format($file*1.23) however can't seem figure out how add <br> before word "chf ". any ideas? the whole code follows: <?php $file = get_field('fl_price'); if(trim($file) == ""){echo 'price on application' ;}else{$conversions = "gbp " . number_format($file*0.84) . "<br />chf " . number_format($file*1.23) ;echo 'eur ' . number_format($file) . "</br><a class=\"wp-tooltip\" title=\" $conversions \">other currencies</a>" ;} ?> $conversions = "gbp " . number_format($file*0.84) . "&#xa;chf " . number_format($file*1.23); echoing $conversions have html-linebreak before chf.

i playing around progress bars ... trying display message when progress bar reaches end of line (100%) ( used raize status bar , tms advprogressbar) raize, code sample seem work : procedure tform1.timer1timer(sender: tobject); begin rzprogressstatus1.percent := rzprogressstatus1.percent +1; if rzprogressstatus1.percent = 100 begin showmessage('yo'); application.terminate; end; end; however,for advprogressbar not because keeps firing messages when position reaches 100.that makes me worry if raize maybe in trouble. procedure tform1.timer1timer(sender: tobject); begin advprogressbar1.position := advprogressbar1.position +1; if advprogressbar1.position = 100 begin showmessage('yo'); application.terminate; end; end; edit : debugger shows : first chance exception @ $00649d6c. exception class $c0000005 message 'access violation @ 0x00649d6c: read of address 0x00000048'. process project1.exe (2928) , stops on following cod...
