java incomparable type when using charAt() -


this question has answer here:

  public void keypressed(keyevent e) {     if(e.getkeycode()==keyevent.vk_enter){         input.seteditable(false);         string quote=input.gettext();         input.settext("");         addtext("you:\t"+quote);         quote=quote.trim();         while(                 quote.charat(quote.length()-1)=="!" ||                 quote.charat(quote.length()-1)=="?" ||                 quote.charat(quote.length()-1)=="."                 ){             quote=quote.substring(0,quote.length()-1);         }         quote=quote.trim(); }

it's giving me incomparable type on quote.charat , need check last character of string if punctuation

quote.charat() returns character. "" defines string.

change single quotes define character:

            quote.charat(quote.length()-1)=='!' ||             quote.charat(quote.length()-1)=='?' ||             quote.charat(quote.length()-1)=='.'

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
