xpath - XPTY0019 A step in a path expression (that is not the last step) is returning atomic values, which is not permitted. ERROR -


i have input structure choice input like: work -choices(developer/tester/support) -developer(inside developer have multiple tools , need initialize in integer) -tools*

i mapped : int count = xpath.evalasint("xpath://\n\n xsd:int(number(count($work/developer/tools)))\n );

but it's throwing error: org.genxdm.xpath.v20.err.concreteerrexception: [xpty0019] step in path expression (that not last step) returning atomic values, not permitted. @

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 <...
