arrays - How would I remove a specific item from a combo box in Java? -

-

i'm using string array populate combo box items. after item has been selected , submitted on button press want remove item combo box. attempt remove selected item string array first, remove items combo box , repopulate string array.

choice string array, cbochoice combobox, strchoice item getting removed

for(int = 0; < choice.length; i++) {         if(choice[i].equals(strchoice)) {             choice[i] = null;             cbochoice.removeallitems();             cbochoice.additem(choice);         }     }

this far i've got, don't know if there simpler method of doing can't seem working.

since have string array , jcombobox have same items in same order, can use jcombobox.getselectedindex() retrieve index location of selected item , remove jcombobox , you're array.

as suggestion, make string array arraylist, it's "smarter" dynamic array , can stay better in synch jcombobox. make sure remove array first, before removing jcombobox, otherwise selected index change.

an arraylist declaration this:

arraylist<string> choice = new arraylist<>();

add content list so:

choice.add(yourchoice);

removing items followed:

if (cbochoice.getselectedindex() > -1) {         choice.remove(cbochoice.getselectedindex());         cbochoice.getselectedindex(); }

hope helps... also, once understand how works, suggest studying comboboxmodel. swing controls have model objects can use add/remove/modify contents without having reference actual control.

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...
