Before executing the body of your own method, be sure to check its arguments for null values. Continue with the execution of the method, only when the arguments are properly checked. Otherwise, you can throw anIllegalArgumentExceptionand notify the calling method that something i...

To fix theNullPointerExceptionin the earlier example, theStringobject should be checked for null or empty values before it is used any further: importorg.apache.commons.lang3.StringUtils;publicclassNullPointerExceptionExample{privatestaticvoidprintLength(String str){if(StringUtils.isNotEmpty(str)) {/...
The pointer must be checked before being dereferenced.Additional ideas and linksWhen considering the idiomatic implementation of the 'offsetof()' operator, one must take into account that a compiler implementation is permitted to use what would be non-portable techniques to implement its functionality....
