Apache thrift: How to assign null as default value? -


how assign default value null in apache thrift interface definition language? tried following, throw fileparseexception. 

struct user {     1: string name,     2: optional string description = "",     3: optional string address = null    //doesn't work.  }

since used optional, use iiset_xxx flags see if particular value set.

in (all?) languages initial field value default, unset value, target languages' equivalent of empty (or null) string anyway. no need set again.

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 <...
