Yes, Day of the Dead is celebrated in Chile. Though it is not a  time to necessarily dress up in a skeleton costume and party-it  is a much more somber holiday. Most busin â¦ esses will be closes and  many people will be at the cemeteries. Not in a sad way either, but  in a happy one.
NULL Statement The NULL statement is a no-op (no operation); it passes control to the next statement without doing anything. In the body of an IF-THEN clause, a loop, or a procedure, the NULL statement serves as a placeholder. For more information, see Using the NULL Statement. Syntax
It is simple, put a null check! Surround your object with if statement like. Object mayBeNullObj = getTheObjectItMayReturnNull(); if (mayBeNullObj != null) { // to avoid NullPointerException. mayBeNullObj.workOnIt(); }. If you think it is so easy and the subject is done, then you are caught wrong.ava API documentation says that NullPointerException can be thrown, when there is an attempt to use null where an object is required. That is you are trying to access a reference where there is no value.
