  • Null check for an object
    2006-03-21 23:04:26  PravinD [View]

    please help me in writing the rule for the following scenario:

    Before invoking any method of an object, a null check should be done.

    Eg:

    String str1 = null;
    String str2 = "ASP";

    str2 = str1.toUpperCase(); // Which will throw NullPointerException.

    So I have to ensure that this line is in the if check. Like,

    String str1 = null;
    String str2 = "ASP";

    if(str1 != null)
    {
    str2 = str1.toUpperCase();
    }

    Any help would be appreciated. Which would be better a Java rule or XPATH rule?
