The Weird and The Wonderful

   

The Weird and The Wonderful forum is a place to post Coding Horrors, Worst Practices, and the occasional flash of brilliance.

We all come across code that simply boggles the mind. Lazy kludges, embarrasing mistakes, horrid workarounds and developers just not quite getting it. And then somedays we come across - or write - the truly sublime.

Post your Best, your worst, and your most interesting. But please - no programming questions . This forum is purely for amusement and discussions on code snippets. All actual programming questions will be removed.

AnswerRe: What is null equal to? [modified] PinprofessionalAfzaal Ahmad Zeeshan25-Aug-14 7:59 
In programming a null object means that this doesn't exist in the memory. For example,
 
int i;
 
if(i == null) {
  MessageBox.Show("Yes, Null!");
} else {
  MessageBox.Show("No, value was added somewhere in the code stack");
}
 
This, would execute if there is no value in i, or the i was never initialized. The code that you're having is something like this
 
// if the variable of value is not initialized
// or contains nothing, does not exist in memory
// .equals(null) is a string method, to check string value
// and has same functionality
if (value == null || value.equals(null)) {
   // then return a string that is NOT null but contains "null"
  return "null";
}
 
The method signature would be like,
 
public string Function1 () {
  // returns a string
}
