Question

In java, Does the following line have a possibility (even 0.01%) to throw a NullPointerException??

public static void handleRequest(String str1){
   if (str1 == null){  // this line throws NPE, how come !! is it a JDK1.5 bug!!
        return null;
   }
   // other staff
}

Actually I am falling some bug in the code and It says that the exact above line in the method throws a java.lang.NullPointerException ?!

Answer 1

No, that line won’t throw a NullPointerException under any circumstances.

But it depends what you mean by “similar”. For example, if your actual line of code is

if (foo.str1 == null)

then you’ll get a NullPointerException if foo is null.
