java - Why isn't my method noticing what is being help by a spot in a 2d array? -

-

so writing program allow book seat on flight. asks user how many rows available, makes 2d array 4 columns , how ever many rows user specifies. program prompts user choose how man seats wants , row , column wants seats be. change value of position in array form "-" "x". works beautifuly, i'm running issues when trying use method cancel reserved seating. have props user, if wants cancel seat , how many, row , column wants cancle. checks see if spot in array has value of "-" or "x" if has "-" displays message saying need input seat reserved , if has "x" changes "-" show open. reason if put in position take or has "x" value says there isn't, did wrong?

here code:

this cancle method

public void cancleseat(string[][] sc, string can, int c, int r, int seats, int an){     fillarray(sc);     if (can.equals("no")){         system.out.println("ok, no cancelations you!");     }     else if (can.equals("yes")){         system.out.println("how many seats cancel?");         = scanner.nextint();         (int = 0; < an; i++){             system.out.println("what row seat in cancle?");             r = scanner.nextint();             r = r - 1;             system.out.println("what colum seat in cancle?");             c = scanner.nextint();             c = c -1;             if (sc[r][c].equals("-")){                 system.out.println("that seat isn't researved pleas pick different seat");                 system.out.println("what row seat in cancle?");                 r = scanner.nextint();                 r = r - 1;                 system.out.println("what colum seat in cancle?");                 c = scanner.nextint();                 c = c - 1;             }             else if (sc[r][c].equals("x") || sc[r][c].equals("x")){                 sc[r][c] = "-";             }         }     } }

and using call in driver class.

system.out.println("would canlce reservations?"); cancle = scanner.next(); seeting cancler = new seeting(numseatsbooking, row, colum, cancle, openseats, answer); cancler.cancleseat(seetingchart, cancle, colum, row, numseatsbooking, answer);

any appreciated! thanks

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
