Http status code managed by which part of web? -


while studying web programming, wondering http status code come web (like apache), (like tomcat), or database server (like mysql).

for example 4xx http status codes client side error , 5xx status codes server side errors. 2 http status codes come web? or web application server?

since http protocol only relevant , handled http server status codes create , sent component.

in contrast database server example has no idea http status code is. has nothing protocol layer.

you can tell http server send specific http status application logic , done. rest apis example rely on that. example php script uses header() function. delegates specific code http server handles communication.

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 <...
